MANHATTAN — Inventing field-effect transistors that achieve high-performance signals with ultra-low electronic noise and laying the foundation for emerging biosensor technologies is the research focus of a Kansas State University assistant professor who has received a $500,000 CAREER award from the National Science Foundation.
Suprem Das, Jeffrey and Joy Lessman — Carl and Mary Ice Keystone research scholar and assistant professor in the industrial and manufacturing systems engineering department in the Carl R. Ice College of Engineering, is investigating the science and technology of atomically thin materials and their nano-engineered structure, including field-effect transistors, a fundamental building block of future bioelectronics. A field-effect transistor uses an electric field to control the flow of current in a semiconductor.
The project, "CAREER: Rational Design of One-Dimensional Contacts to Two-Dimensional Atomically Thin Heterostructure for High-Performance and Low Noise Field-Effect Transistors and Biosensors," aims to study field-effect transistors with two-dimensional atomically thin materials with unique one-dimensional metal contacts designed with high-performance and low-noise characteristics.
Das is investigating the use of graphene, hexagonal boron nitride and transition metal di-chalcogenides to form atomically thin field-effect transistors.
"Given their unprecedented physics and chemistry at the atomic level, these devices will revolutionize their use in electronics, communication and cyber systems, as well as in health care and environmental sensing," Das said.
Additionally, the project will train diverse graduate and undergraduate students in micro-nanoscale science and engineering, while the results from this project will be integrated in interdisciplinary educational activities at K-State.
