Postdoctoral Research Associate - 2D Materials & Devices

Brookhaven National Laboratory • Upton, NY

5d • Onsite

About The Position

The Center for Functional Nanomaterials (CFN) at Brookhaven National Laboratory is seeking a Postdoctoral Research Associate to conduct novel research on 2D material heterostructures for developing steep-slope transistors for energy-efficient microelectronics. This role is part of a DOE Microelectronics Science and Research Center (MSRC) project. You will investigate the materials and device physics of 2D materials and heterostructures, perform nanofabrication and electrical characterization using state-of-the-art facilities, and analyze the influence of atomic defects on device characteristics. The project also involves integrating 2D-3D and 2D-membrane semiconductor heterostructures. You will work under the supervision of Dr. Chang-Yong Nam.
