In January 2018 I was appointed the Associate Dean of Research, Graduate Programs and Natural Sciences in the College of Arts and Sciences and promoted to full Professor. I have been engaged in many college initiatives while preparing to bring my Hybrid Electronics & Characterization Laboratory (HECL) 2.0 online.
We use molecules to build electronic circuits that can be used as switches, diodes, wires, transistors and memory elements similar to conventional silicon integrated devices. Molecular electronics offer size reduction in electronics and molecular level control of properties that can reduce power consumption.
To confirm the presence of molecules in an electric circuit, we use inelastic electron tunneling spectroscopy (IETS). At 4.2K, this technique is used to identify the vibration modes (frequency) of molecules that are positioned in a nanoscale gap. The gap is formed by electromigration (i.e. 'burning' of a gold nanowire in high vacuum).
We explore machine learning to combine experimental research data, high-throughput computation, and artificial intelligence to build a comprehensive database for porphyrins to predict their electrical properties. Porphyrins have highly tunable electrical and optical properties that can be used in quantum information technologies.
Since 2010 we have published articles in the area of molecular electronics and electron transport in nanoscale systems.
