Postdoctoral Research Associate 2D Materials & Devices

Organization Overview: The Center for Functional Nanomaterials (CFN) at Brookhaven is a DOE-funded national scientific user facility, offering users a supported research experience with top-caliber scientists and access to state-of-the-art instrumentation. The CFN mission is advancing nanoscience through frontier fundamental research and technique development and is the nexus of a broad collaboration network. Each year, CFN staff members support the research of nearly 600 external facility users.Three strategic nanoscience themes underline the CFN scientific facilities: The CFN conducts research on nanomaterial synthesis by assembly designing precise architectures with targeted functionality by organizing nanoscale components. The CFN researches and applies platforms for state-of-the-art techniques for Accelerated Nanomaterial Discovery, integrating synthesis, advanced characterization, physical modeling, and computer science to iteratively explore a wide range of material parameters. The CFN develops and utilizes advanced capabilities for studies of Nanomaterials in Operando Conditions for characterizing materials and reactions at the atomic scale in real-world environments.Position DescriptionThe CFN is seeking a talented Postdoctoral Research Associate to conduct novel research investigating 2D material heterostructures for developing steep-slope transistors for energy-efficient microelectronics applications as a part of a DOE Microelectronics Science and Research Center (MSRC) project. You will explore the materials and device physics of 2D materials and associated heterostructures, such as those based on 2D transition-metal dichalcogenides (TMDCs), and perform nanofabrication and electrical characterization of 2D heterostructure devices using CFN's state-of-the-art Facilities, such as Quantum Materials Press (QPress) and Nanofabrication Facilities, to unravel the influences of atomic defects in 2D materials on the steep-slope device characteristics and performance. This project also aims to investigate the integration of 2D-3D and 2D-membrane semiconductor heterostructures utilizing the materials provided by other external MSRC project team members. You will work under the supervision of Dr. Chang-Yong Nam (Electronic Nanomaterials Group).Essential Duties and Responsibilities: * You will develop, fabricate, and characterize 2D heterostructures applicable to steep-slope electrical devices based on state-of-the-art 2D materials such as 2D TMDCs and graphene. * You will perform in-depth materials characterization on 2D materials, and electrically characterize the fabricated 2D devices, especially their transistor characteristics, as a function of temperature and the materials characteristics. * You will explore new materials, device structure & physics, and patterning methods for improving the performance of 2D steep-slope devices. * You will perform integration and nanofabrication of 2D-3D and 2D-membrane semiconductor heterostructures using the materials provided by the external MSRC project team members. * You will collaborate with scientific staff with diverse backgrounds including materials science, nanofabrication, and device fabrication and physics. * You will disseminate research findings via paper publications and external presentations.Required Knowledge, Skills, and Abilities: * You have a Ph.D. in a relevant discipline (Materials Science, Physics, Electrical Engineering, or a related engineering discipline), conferred within the past five years or to be completed prior to the starting date. * You have demonstrated experimental expertise in 2D material heterostructure device fabrication and electrical characterization under various temperatures, including 2D materials mechanical exfoliation/transfer and low-temperature measurements using a cryostat, as well as associated materials and device physics. * You have demonstrated experimental experience in nanofabrication proces
