This book summarizes the current status of theoretical and
experimental progress in 2 dimensional graphene-like monolayers and
few-layers of transition metal dichalcogenides (TMDCs).
Semiconducting monolayer TMDCs, due to the presence of a direct
gap, significantly extend the potential of low-dimensional
nanomaterials for applications in nanoelectronics and
nano-optoelectronics as well as flexible nano-electronics with
unprecedented possibilities to control the gap by external stimuli.
Strong quantum confinement results in extremely high exciton
binding energies which forms an interesting platform for both
fundamental studies and device applications. Breaking of spatial
inversion symmetry in monolayers results in strong spin-valley
coupling potentially leading to their use in valleytronics.
Starting with the basic chemistry of transition metals, the reader
is introduced to the rich field of transition metal
dichalcogenides. After a chapter on three dimensional crystals and
a description of top-down and bottom-up fabrication methods of
few-layer and single layer structures, the fascinating world of
two-dimensional TMDCs structures is presented with their unique
atomic, electronic, and magnetic properties. The book covers in
detail particular features associated with decreased dimensionality
such as stability and phase-transitions in monolayers, the
appearance of a direct gap, large binding energy of 2D excitons and
trions and their dynamics, Raman scattering associated with
decreased dimensionality, extraordinarily strong light-matter
interaction, layer-dependent photoluminescence properties, new
physics associated with the destruction of the spatial inversion
symmetry of the bulk phase, spin-orbit and spin-valley couplings.
The book concludes with chapters on engineered heterostructures and
device applications such as a monolayer MoS2 transistor.
Considering the explosive interest in physics and applications of
two-dimensional materials, this book is a valuable source of
information for material scientists and engineers working in the
field as well as for the graduate students majoring in materials
science.
A state-of-the-art description of metastability observed in
chalcogenide alloys is presented with the accent on the underlying
physics. A comparison is made between sulphur(selenium)-based
chalcogenide glasses, where numerous photo-induced phenomena take
place entirely within the amorphous phase, and tellurides where a
reversible crystal-to-amorphous phase-change transformation is a
major effect. Applications of metastability in devices?optical
memories and nonvolatile electronic phase-change random-access
memories among others are discussed, including the latest trends.
Background material essential for understanding current research in
the field is also provided.
