Atomic-Precision Synthesis of 2D Materials and Heterostructures

The realization of atomically thin circuits and systems relies on understanding and synthesis of 2D layered materials and their heterostructures. We investigate the materials science of 2D material growth to enable the construction of both in-plane and out-of-plane heterostructures with tailored geometries and functionalities. Using metal-organic chemical vapor deposition (MOCVD), we achieve wafer-scale synthesis with precise control over composition, crystal phase, morphology, thickness, and epitaxial alignment.

Novel Electronics and Optoelectronics in 2D Nanostructures

We explore how heterostructures, interfaces, strain, and morphology in 2D materials give rise to novel electronic and optical phenomena. Leveraging heterostructures with atomic precision, we design and demonstrate energy-efficient devices such as field-effect transistors, tunnel junctions, photodetectors, imagers, light-emitting diodes, and solar cells.

Scalable Integration for Circuits and Systems

We translate materials and device-level innovations into functional circuits and systems. Our approach focuses on wafer-scale synthesis, processing, and heterointegration of 2D materials to enable circuit-level applications with enhanced energy efficiency and functionality.
