1. Atomically Precise Carbon-Based Nanoelectronics for High-Performance and Energy-Efficient Logic Technologies
This area of our research focuses on advancing carbon-based nanoelectronic devices, specifically field-effect transistors (FETs) using bottom-up synthesized graphene nanoribbon (GNR) semiconductor channels. Our goal is to develop high-performance, energy-efficient logic technologies with GNRFETs. By leveraging expertise from materials science, chemistry, physics, electrical engineering, and computer science, we aim to understand charge transport in GNRs and address critical challenges in integrating GNRs into FETs at both device and circuit levels, which include developing low-resistance contacts, integrating novel high-k 2D dielectrics, fabricating wafer-scale aligned and pitch-controlled devices, and achieving monolithic 3D integration.
2. Design of Topological Acoustic Wave Devices for Advanced Radio-Frequency (RF) Technologies
In this project, we focus on the design micro/nano-fabrication, and characterization of novel topological acoustic (TA) wave devices to advance radio-frequency (RF) technologies. We investigate the complex dynamics of acoustic wave propagation and control through a wide range of nano-micro structures with precisely engineered topologies on piezoelectric substrates, created using cutting-edge laser ablation techniques. By integrating advanced topological principles into these structures, we aim to develop proof-of-concept TA wave devices that could redefine the performance and capabilities of RF technology.
3. Investigation of Carrier Transport and Leaching Mechanisms in Chalcopyrite Mineral for Improved Copper Extraction
In this project, we aim to advance the fundamental understandin of chalcopyrite semiconductor minerals and their leaching behavior to optimize copper extraction processes. We explore how variations in chalcopyrite's mineral composition impact its semiconductor properties and, in turn, its leaching characteristics. Our work involves developing and using precise methods to measure the semiconductor properties of chalcopyrite samples in various forms, including powders and bulk materials. By clarifying the connections between chalcopyrite's composition, its electronic properties, and its leaching dynamics, we aim to refine copper extraction techniques and advance more efficient mineral processing methods.
