Overview
Background
Dr Mile Gao is a physicist specialising in condensed matter physics, with a focus on charge carrier dynamics in organic semiconductor devices. His research advances the development of novel measurement techniques to improve the understanding of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). He has pioneered several charge carrier mobility measurement methods, including Metal-Insulator-Semiconductor CELIV (MIS-CELIV), photo-MIS-CELIV, injection-CELIV, and photo-injection-CELIV. These techniques enable precise characterisation of charge transport and generation processes in diode-like structures, addressing key challenges in organic optoelectronics.
Dr. Mile's work has led to significant insights into charge injection, extraction, and mobility in organic semiconductors, with implications for improving device efficiency and stability. His research is highly interdisciplinary, combining physics, materials science, and device engineering.
He has published extensively in high-impact journals and holds a patent for his contributions to the field. As an ARC DECRA Fellow at The University of Queensland, he also teaches and supervises students in advanced experimental techniques for semiconductor characterisation.
