Exploring optical and optoelectronic properties in transition metal dichalcogenides
Abstract/Contents
- Abstract
- The interest in van der Waals (vdW) materials has been growing steadily over the past two decades due to their immense potential in electronics and optics. Corresponding, we have access to a growing library of vdW materials with diverse properties. Since these materials only have strong chemical bonds in two dimensions, these materials can be arbitrarily layered to combine and create new properties. Within the vdW library, direct band-gap monolayered (1L) transition metal dichalcogenide (TMDC) semiconductors of the form MX\(_2\) (M= Mo, W and X= S, Se, or Te) have attracted attention for their strongly tunable electronic and optical properties. Additionally, the lack of inversion symmetry in monolayer TMDCs results in unique spin and momentum properties usable in spintronics and the emerging field of valleytronics. Furthermore, due to the reduced Coulomb screening inherent to 2D materials, TMDCs exhibit strongly-bound excitons (correlated electron-hole pairs) which can be manipulated and used to study the material itself or even to store and convert information. This thesis presents an exploration of the properties of TMDCs and their combinations in relationship to their potential for device application.
