Dr. Cham Heng Angus Li's area of technical expertise focuses on synthesis, fabrication and characterization of nanomaterials to be used in light-emitting diode (LED) devices.  He researched both the active material (halide perovskites in 2D thin-films and 0D nanocrystals) and the transport layers.

During his PhD study, Dr. Li mainly worked on improving blue perovskite LEDs' efficiency and stability with composition and device engineering.

Dr. Li is experienced with various optical and electrical characterizations such as UV-Vis absorption spectroscopy, photoluminescence measurements, ellipsometry, X-ray crystallography, x-ray photoelectron spectroscopy, scanning electron microscopy with energy disperse X-ray spectroscopy (EDS), and atomic force microscopy. He also collaborated with physicists in HKUST to perform ultrafast spectroscopies, including transient absorption and time-resolved photoluminescence (TRPL). He is also familiar with LED characterizations with current-voltage (JV) measurements and spectrometer coupled with integrated sphere or photo-detectors.

Prior joining Exponent, Dr. Li worked as research assistant in department of chemistry in City University of Hong Kong, where he synthesized organic small molecules to be used in organic solar cells. Dr. Li also worked briefly in a local marketing and public relationship company to assist branding building for companies from Asia and Europe.
