Short presentation

Currently, I am working on dynamic optical and electrical properties of electrochromic amorphous tungsten oxide thin films under the supervision of Prof. Gunnar Niklasson. Here, we aim to develop new ways of describing and understanding the coloration processes in electrochromic materials. Particularly, we are interested in the implementation of frequency-dependent techniques for the study of electrochromic materials; namely, simultaneous electrochemical and color impedance measurements.

Keywords: optics solid state physics electrochromism
