Research Interest

Understanding the Physics and Chemistry of Single Molecule Junctions

The research in my group strives to construct measure and understand the physics and chemistry of single molecule electrical junctions. This research is crucial for the advancement of future nanoelectronic devices.

Current research in the group is divided into two areas:

  1. Measurement of the thermophysical properties of molecular junctions such as thermovoltage, and heat conduction. Understanding heat conduction through molecular junctions is important as heat capacity of molecules is extremely small as a result heat dissipation in molecular junctions is expected to drastically affect their stability and performance.
  2. Molecular spintronics: Theory suggests that the tunneling magnetic resistance (TMR), i.e., the efficiency of spin tunneling without flipping, in molecular junctions could be as high as 500%, while standard solid state devices are operating at 40%. Experimental verification of this prediction is underway. Highly efficient TMR elements will enable to develop universal ‘on-chip’ memory technology.

Since typical energy scales of molecules are in the optical and infrared regime, where today’s laser technology provides a wealth of coherent light sources, future research in my group will focus on the various ways by which lasers could be used to affect and direct currents through single molecule junctions.
