Biography

I deal with multi-physics simulations of semiconductor-based opto-electronic devices using in-house TCAD (technology computer aided design) tools developed by our research group. Specifically, I deal with a specific type of LED, operating in the UVC band (Ultraviolet C Light Emitting Diodes), useful in many applications ranging from sterilization to biosensing. This type of devices can integrate a tunnel junction to deal with technological problem involving p-dopants for nitride-based semiconductors. In this view, to properly simulate such devices, it is required to analyse them from the quantum transport standpoint (non-equilibrium Green's function approach for electrons and holes, coupled together) and to the semiclassical electronic transport standpoint (drift-diffusion). The aim of this project is to obtain a combined description of the device that can approximate as much as possible the real behaviour of real UVC-LEDs in terms of IV characteristic.
