Summary of Interests
Charge and energy transport in nanocrystal films: metal-insulator transition and optical properties

About My Work

I study the electronic and optical properties of nanocrystal (NC) networks under the supervision of Uwe Kortshagen in the ME department, collaborating closely with Boris Shklovskii.

First, I study the metal-insulator transitions (MIT) in NC networks. We individually tune the inter-NC contact area and the electron density by flashing the films with a high powered xenon lamp, allowing us to optimize the electronic properties of NC films.

In addition, I study inter-particle exciton dynamics in NCs using time resolved emission spectroscopy. I am currently at Los Alamos National Lab for the 2018 calendar year on a DoE Fellowship, doing ultrafast spectroscopy in Victor Klimov's group.
