Two dimensional materials such as graphene, boron nitride and transition metal dichalcogenide (TMDCs) monolayers have arisen as a new class of materials with unique properties at monolayer thickness. Their electrical, electronic and optical properties are of great importance for a variety of applications in optoelectronics as light emitters, detectors, and photovoltaic devices. This work focuses on MoS2 and WS2, which are two important members of the TMDC class of materials. The properties of monolayer MoS2 and WS2 are investigated as well as the properties of bulk MoS2 and WS2 to provide an understanding …

Theses
Transition-metal dichalcogenides (TMDC) crystals have emerged as a new class of semiconductors that display distinctive properties at monolayer thickness. Their electrical, electronic and optical properties are of particular interest and importance for applications in optoelectronics as light emitters, detectors, and photovoltaic devices. Monolayer MoSe2 and WSe2 have an intrinsic band-gap in the visible region of the solar spectrum (400nm - 700nm) which makes them distinct from other 2-D materials like graphene.
In this study, the electrical, electronic and optical properties of monolayer and bulk MoSe2 and WSe2 are studied. The electronic band structures are presented for …
