Congratulations to Ph.D. student Mr. CHIEN Yu-Chieh, supervised by Associate Professor Ang Kah-Wee from the Department of Electrical and Computer Engineering, won the Young Researcher Award at the 2022 International Conference on Solid-State Devices and Materials (SSDM).
The SSDM Young Researcher Award is awarded to the first authors of excellent papers presented at the previous year’s SSDM. Authors who are 33 years old or younger as of April 1st of the year following the conference in which the paper was presented are eligible for the award.
The conference covers a broad spectrum of topics related to solid-state devices and materials, extended to those for the multidisciplinary and emerging research fields. The team works on developing a universal extraction method for mobility and contact resistance in two-dimensional-based semiconductors. The paper entitled “Universal Method on Charge Carrier Mobility and Series Resistance Extraction in Two‐Dimensional Field‐Effect Transistors” establishes a universal method that can independently determine the intrinsic mobility and series resistance in two-dimensional field-effect transistors. The extraction manifests high accuracy with a broad temperature range from a cryogenic temperature of 3K to 300K, which can be sustained even when the carrier conduction is dominated by the metal-2D contact. Technology Computer-Aided Design (TCAD) simulation is performed to theoretically verify the resolution limit of our extraction framework. The merit of this method is reinforced by its applicability to various emerging 2D channel materials with top and bottom gate configurations.
