Photo-Excited Charge Collection Spectroscopy

by Seongil Im Youn-Gyoung Chang Jae Hoon Kim

Solid state field-effect devices such as organic and inorganic-channel thin-film transistors (TFTs) have been expected to promote advances in display and sensor electronics. The operational stabilities of such TFTs are thus important, strongly depending on the nature and density of charge traps present at the channel/dielectric interface or in the thin-film channel itself. This book contains how to characterize these traps, starting from the device physics of field-effect transistor (FET). Unlike conventional analysis techniques which are away from well-resolving spectral results, newly-introduced photo-excited charge-collection spectroscopy (PECCS) utilizes the photo-induced threshold voltage response from any type of working transistor devices with organic-, inorganic-, and even nano-channels, directly probing on the traps. So, our technique PECCS has been discussed through more than ten refereed-journal papers in the fields of device electronics, applied physics, applied chemistry, nano-devices and materials science, finally finding a need to be summarized with several chapters in a short book. Device physics and instrumentations of PECCS are well addressed respectively, in the first and second chapters, for the next chapters addressing real applications to organic, oxide, and nanostructured FETs. This book would provide benefits since its contents are not only educational and basic principle-supportive but also applicable and in-house operational.

Photoacoustic Imaging and Spectroscopy (Optical Science and Engineering)

by Lihong V. Wang

Photoacoustics promises to revolutionize medical imaging and may well make as dramatic a contribution to modern medicine as the discovery of the x-ray itself once did. Combining electromagnetic and ultrasonic waves synergistically, photoacoustics can provide deep speckle-free imaging with high electromagnetic contrast at high ultrasonic resolution and without any health risk. While photoacoustic imaging is probably the fastest growing biomedical imaging technology, this book is the first comprehensive volume in this emerging field covering both the physics and the remarkable noninvasive applications that are changing diagnostic medicine.

Photoassociation of Ultracold CsYb Molecules and Determination of Interspecies Scattering Lengths (Springer Theses)

by Alexander Guttridge

This thesis lays the groundwork for producing a new class of ultracold molecule by associating an alkali-metal atom and a closed-shell alkaline-earth-like atom, specifically Cs and Yb. Such molecules exhibit both a magnetic dipole moment and an electric dipole moment in their ground state. This extra degree of freedom opens up new avenues of research including the study of exotic states of matter, the shielding of molecular collisions and the simulation of lattice spin models.In detail, the thesis reports the first and only ultracold mixture of Cs and Yb in the world, giving details of the methods used to cool such contrasting atomic species together. Using sensitive two-colour photoassociation measurements to measure the binding energies of the near-threshold CsYb molecular levels in the electronic ground state has allowed the previously unknown scattering lengths to be accurately determined for all the Cs–Yb isotopic combinations. As part of this work, the one-photon photoassociation of ultracold Cs*Yb is also studied, yielding useful information on the excited-state potential. Knowledge of the scattering lengths enables a strategy to be devised to cool both species to quantum degeneracy and, crucially, determines the positions of interspecies Feshbach resonances required for efficient association of ground-state CsYb molecules. With these results, the prospect of bringing a new molecule into the ultracold regime has become considerably closer.

Photobiogeochemistry of Organic Matter

by Davide Vione Khan M.G. Mostofa Takahito Yoshioka Abdul Mottaleb

Photoinduced processes, caused by natural sunlight, are key functions for sustaining all living organisms through production and transformation of organic matter (OM) in the biosphere. Production of hydrogen peroxide (H2O2) from OM is a primary step of photoinduced processes, because H2O2 acts as strong reductant and oxidant. It is potentially important in many aquatic reactions, also in association with photosynthesis. Allochthonous and autochthonous dissolved organic matter (DOM) can be involved into several photoinduced or biological processes. DOM subsequently undergoes several physical, chemical, photoinduced and biological processes, which can be affected by global warming. This book is uniquely structured to overview some vital issues, such as: DOM; H2O2 and ROOH; HO*; Degradation of DOM; CDOM, FDOM; Photosynthesis; Chlorophyll; Metal complexation, and Global warming, as well as their mutual interrelationships, based on updated scientific results.

Photocatalysis for Heterocycle Formation and Functionalisation (Topics in Heterocyclic Chemistry #62)

by Wen-Jing Xiao

Heterocyclic compounds are an important class of organic chemicals that feature one or more heteroatoms in their ring systems. Such compound class have played an important role in our daily lives, as they are ubiquitous in natural products, pharmaceuticals, and other biologically active molecules. Many heterocyclic scaffolds have been identified as privileged structural units in pharmacologically active compounds. According to statistics, more than 90% of novel pharmaceuticals contain at least one heterocycle. Advances in modern synthetic techniques, such as organocatalytic cycloadditions, metal-catalyzed cross-coupling reactions, have offered many efficient and rapid approaches for assembly of diverse heterocycles of various ring sizes. However, given increasing need for expansion of the available drug-like chemical space and from both environmental and economical viewpoints, it is still highly desirable to develop new efficient and practical methodologies toward heterocycle synthesis and functionalization under “green and sustainable” conditions. Photocatalysis is emerging as a powerful tool to access diverse high-energy intermediates in a controlled and selective fashion, and capable of promoting numerous challenging bond formation and novel chemical transformation. This re-merging catalytic strategy fits with green chemistry principles and has significantly spurred many innovative approaches that use of low energy photons as a controllable energy source to enable heterocycle formation and functionalization under mild conditions. In this book, we have tried to cover some interesting aspects of the development of photocatalytic reactions that are aimed to construct diverse heterocyclic compounds. Specifically, this major content is devoted to the following research topics, including N-heterocycle formation (Chapters 1, 4, and 6), functionalization of N-heterocycles (Chapters 2, 3, and 8), chiral heterocycle formation (Chapter 5), dearomatization of heterocycles (Chapter 7), fused thiophene formation and functionalization (Chapter 9), construction of axially chiral heterocyclies (Chapter 10), and photoinduced biocatalytic heterocycle formation (Chapter 11). It is our hope that this book, in addition to being of interest to practitioners of medicinal chemistry and organic synthesis who need an introduction to this area, will also be found inspiriting and stimulating by undergraduate and graduate students.

Photocatalytic Hydrogen Fuel Generation: Designing Highly Efficient Semiconductor Materials (Green Energy and Technology)

by Hairus Abdullah

This book highlights crucial parameters and strategies in photocatalytic water splitting. The process utilizes light energy to drive the separation of water into hydrogen and oxygen with the help of a photocatalyst. The efficiency and performance of catalytic activities are determined by various parameters supported by material characterizations. Commonly, the catalytic performances in visible-light photocatalytic water splitting are governed by bandgap energy, surface area, crystal structure, charge carrier dynamics, catalyst loading, cocatalyst, pH of solution, and reaction temperatures. However, covering all the requirements to obtain a highly efficient catalytic activity is an impossible task.
