Description

This postdoctoral research opportunity at the Naval Research Laboratory (NRL) focuses on developing and exploring a mathematical theory to describe a new process for creating semiconductor nanostructures. These nanostructures consist of an alloy of two compound semiconductors separated into two regions with a continuously changing gradation between them, resulting in a smooth variation in conduction and valence bands across the nanostructure.

By controlling parameters in this process, various profiles can be created that enhance electronic and optical properties, including increased light emission and absorption, reduced nonradiative Auger recombination rates, and ultrafast carrier separation. The research will leverage recent advances in nanoscale cation exchange, specifically employing a novel method called "arrested cation exchange."

The program seeks a mathematically trained, motivated postdoctoral researcher experienced in working with systems of coupled diffusion equations to investigate their implications for creating alloyed nanocrystals.
