Kim Michelle Lewis, PhD, Professor of Physics/Associate Dean

Welcome

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.

What to Expect from HECL 2.0

Characterization of Molecular Electronics

Low Temperature Electron Transport Measurements

Low Temperature Electron Transport Measurements

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. 

Low Temperature Electron Transport Measurements

Low Temperature Electron Transport Measurements

Low Temperature Electron Transport Measurements

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). 

A New Project: Machine Learning

Low Temperature Electron Transport Measurements

A New Project: Machine Learning

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.  

Publications

Since 2010 we have published articles in the area of molecular electronics and electron transport in nanoscale systems.
