Research Interest

My research interests include study of novel optoelectronic materials at the nanoscale and their application in solid-state electronics. I am working on the control of growth orientation using quantum confinement in layered one-dimensional semiconductors, which could enable enhanced device performance, reduced variability and coherent integration with silicon photonics at room temperature processing. 

My previous experience include improving the thermal stability of tellurium for p-type channel material with feasible back-end-of-line integration with silicon electronics. Before that, I studied the effect of charging on core-shell quantum dots, to gain insight into the degradation mechanism of these nanoparticles in light emitting devices. In addition, I studied electroluminescence in silicon, an unlikely phenomenon for indirect bandgap silicon. We uncover the origin of its electroluminescence from hot carrier effects, when bipolar carriers are injected into the material with high slew rate AC pulses.
