Intrinsic circular polarization in centrosymmetric stacks of transition - metal dichalcogenide
Submitted for the MAR15 Meeting of The American Physical Society Intrinsic circular polarization in centrosymmetric stacks of transition-metal dichalcogenide1 QIHANG LIU, XIUWEN ZHANG, ALEX ZUNGER, University of Colorado, Boulder — The circular polarization (CP) that the photoluminescence inherits from the excitation source in n monolayers of transition-metal dichalcogenides (MX2)n has been pre...
متن کاملIntrinsic disorder in graphene on transition metal dichalcogenide heterostructures.
Semiconducting transition metal dichalchogenides (TMDs) are a family of van der Waals bonded materials that have recently received interest as alternative substrates to hexagonal boron nitride (hBN) for graphene, as well as for components in novel graphene-based device heterostructures. We elucidate the local structural and electronic properties of graphene on TMD heterostructures through scann...
متن کاملAging of Transition Metal Dichalcogenide Monolayers.
Two-dimensional sheets of transition metal dichalcogenides are an emerging class of atomically thin semiconductors that are considered to be "air-stable", similar to graphene. Here we report that, contrary to current understanding, chemical vapor deposited transition metal dichalcogenide monolayers exhibit poor long-term stability in air. After room-temperature exposure to the environment for s...
متن کاملTwo-dimensional transition metal dichalcogenide (TMD) nanosheets.
This special issue is about two-dimensional transitionmetal dichalcogenides (2DTMDs), a family of materials consisting of over 40 compounds with the generalized formula of MX2, where M is a transition metal typically from groups 4–7, and X is a chalcogen such as S, Se or Te. Bulk TMDs have been widely studied over several decades because it is possible to formulate compounds with disparate elec...
متن کاملSymmetry Based Properties of the Transition Metal Dichalcogenide Nanotubes
The full geometrical symmetry groups (the line groups) of the monolayered, 2Hb and 3R polytypes of the inorganic MoS2 and WS2 microand nanotubes of arbitrary chirality are found. This is used to find the coordinates of the representative atoms sufficient to determine completely geometrical structure of tubes. Then some physical properties which can be deduced from the symmetry are discussed: el...
