1. Atomically Precise Graphene Nanoribbon-Based Transistors for High-Performance Logic Technologies
In this project, we investigate electrical charge transport in bottom-up synthesized semiconducting graphene nanoribbons (GNRs), a chemically versatile class of low-dimensional quantum materials. Theoretical studies suggest that GNRs exhibit exceptional charge mobility and current-carrying capabilities, making them highly promising as semiconducting channels in field-effect transistors (FETs). In principle, GNR-based FETs could significantly surpass traditional silicon transistors in performance and energy efficiency, offering advantages across several orders of magnitude while unlocking novel functionalities beyond silicon’s capabilities. However, their experimental performance remains far below theoretical expectations. To bridge this gap, we seek to deepen our understanding of charge transport in GNRs and develop strategies to overcome these limitations, ultimately advancing their potential for high-performance logic transistor technologies and other emerging nanoelectronic applications.
2. Topological Acoustic Wave Devices for Advanced Radio-Frequency and Sensing Technologies
In this project, we design, fabricate, and characterize novel topological acoustic (TA) wave devices. Our goal is to develop proof-of-concept devices that leverage the principles of topological physics to achieve topological protection, enabling robust and precise control of acoustic waves on demand. To achieve this, we study the fundamental interactions between topology and acoustic wave dynamics, designing structures with varying patterns and topologies that serve as platforms for topological sound propagation. Ultimately, we aim to advance radio-frequency (RF) and sensing technologies, making them more energy-efficient, higher performing, and enabling novel multifunctional capabilities previously unattainable.
3. Exploring the Semiconductor Properties and Their Potential Link to Slow Leaching Behavior of Chalcopyrite for Improved Copper Extraction
In this project, we are studying the semiconductor behavior of Chalcopyrite (CuFeS2) with varying compositions, including properties such as Hall mobility, carrier concentration, type, and resistivity, while also developing reliable methods and reporting practices. Our primary goal is to understand how these semiconductor properties influence chalcopyrite’s slow leaching behavior in copper extraction. By gaining deeper insight into these fundamental mechanisms, the project aims to improve copper recovery while minimizing environmental impact.
