Tailoring the Properties of Heterostructures of Monolayers: Epitaxial Growth and Doping
Abstract
Heterostructures of semiconductor materials, which provide enhanced electrical and optical characteristics well beyond that of each individual constituent material, have been the key enabling element in modern telecommunication, energy-efficient displays, and energy harvesting technologies. This project explores a new approach to synthesize heterostructures made of sheets of two-dimensional materials, in which atoms within a sheet form strong bonds but interactions between the layers are very weak. Atomic-resolution imaging and calculations are carried out to understand how this characteristic anisotropic bonding facilitates the growth and assembling of the single atomic layers similar to LEGO blocks, thus allowing the design and synthesis of new materials with tailored properties and functionalities beyond the limits of materials that currently exist in nature.
