Abstract

Two-dimensional transition metal dichalcogenides (2D TMDCs) are promising candidates for the formation of planar optoelectronic devices on a large range of substrates (including flexible substrates). In this talk, different techniques for the synthesis of TMDC alloys with high degree of control over the in-plane spatial profile of the alloying process for precise tuning of the optoelectronic properties of the resulting material will be demonstrated. The main challenges in using this process for forming high-quality lateral heterostructures (e.g., for the formation of quantum wells and quantum dots in a single-layer 2D material), especially the effect of alloying-induced strain and its impact on the structural and optoelectronic properties of TMDC alloys, will be discussed in depth; and solutions to address this challenge will be presented.
