2D (Two Dimensional) Heterostructures for Integrated Nano Optoelectronics
Abstract
The BRI project aims to investigate the use of novel nano-optoelectronic systems based upon two dimensional (2D) heterostructures to realize breakthrough technologies for optical communications. The 2D heterostructure devices feature atomically-thin transition metal dichalcogenides (TMDs) and black phosphorous, in combination with graphene and boron nitride. During this award period, we have made exciting progress towards the objective, including material innovation, device engineering, and development and investigation of 2D optoelectronics and integration with nano-photonic structures. In specific: (1) We have developed layer by layer growth of a wide range of TMDs by both MBE and physical vapor transport. (2) We have developed both TMD based optoelectronic devices near visible wavelength range and black-phosphorus based mid-infrared optoelectronics. These devices include light emitting diodes (LEDs), nano-cavity integrated monolayer LEDs, 2D heterostructure LEDs, optical and electrical driven single quantum emitters in monolayer WSe2, and mid-Infrared black phosphorus photodetector with electrical control; (4)development of novel materials and device concepts, such as the discovery of 2D topological insulators for low energy dissipation devices.
