Research scope

My current effort can be classified into 2 main parts: first, combining an effort in material science with the development and implementation of state-of-the-art ultrafast (predominantly Terahertz-based) spectroscopies, we aim to shed light on the low-energy excitations (e.g. bounded electron-hole pair or so-called excitons, polarons or lattice-deformation dressed charges) in low-dimensional solids, ultrafast charge transport phenomenon (e.g. hot carrier cooling and transport) and charge transfer across the material interfaces for solar energy and optoelectronic devices. Second, I am fascinated by ion transport effects and many-body ion effects in the nanoscale ion channels. The key question that we would like to adress is the confined induced ion correlation and its impact on nonlinear ion transport phenomena at nanoscale. 

With understanding the fundamentals of charge and ion dynamics, we aim to provide insights and guide towards optimization of energy-harvesting and storage devices (e.g. photochemical cell, photovoltaics and battery etc.).
