RESEARCH AND INTERESTS
Dr. Yang’s research interest focuses on functional electronic devices (solar cells, thin film transistors, light emitting devices) which hold promise for cost effective applications. The research is a comprehensive system involving rational design of materials (organic semiconductors, hybrid perovskites, inorganic nanomaterials), the control of film morphology, crystal growth, fundamental understanding of electrical properties of the new materials and structures, understanding of nanoscale structure-property relationship, control and understanding of interface s in devices (organic/organic, organic metal etc.), new device architecture development etc.
