Research Interest:

Our research group is focused on developing high-performance field-effect transistors (FETs) using liquid metal oxide-assisted (LMO) gate dielectrics (Ga2O3, HfO2, and ZrO2). We explore the application of LMOs in various device architectures, including 2D semiconductors (TMDs), self-assembled monolayers (SAMs), organic, inorganic, and micro-nano-crystal systems. 

Our interdisciplinary approach combines chemical synthesis, self-assembly, device fabrication, and electrical characterization to understand the charge transport phenomenon underlying LMO-based FETs and also to produce low-power-based transistors. Our research aims to contribute to the development of next-generation electronic devices with enhanced performance, efficiency, and potential applications in areas such as sensors, light-emitting field effect transistors, and memory devices.

In specific our group focuses on

1. High k-dielectric metal oxides for 2D Organic/inorganic and semiconductors

2. Liquid metal oxide-assisted molecular tunnel junctions

3. Self-assembly of organic/inorganic micro-crystals for optoelectronics
