Weihua Han is a Professor at the School of Physical Science and Technology, Lanzhou University, where he supervises PhD students in Condensed Matter Physics and Electronic Science and Technology, and advises professional degree students in Integrated Circuits. Dr. Han received his bachelor's degree in Microelectronics from Lanzhou University in 2003, and in 2008, he earned his PhD in Condensed Matter Physics (Microelectronic Materials and Devices) from the same institution. He has remained at Lanzhou University since then. Dr. Han has conducted research at several prestigious institutions, including postdoctoral research at the University of Minho, Portugal, and at the University of Rome Tor Vergata, Italy. He was also a visiting scholar at the Georgia Institute of Technology, USA, and a visiting scientist at Oak Ridge National Laboratory, USA. In 2018, he was recognized as a Taishan Scholar Youth Expert by Shandong Province. Dr. Han's research is rooted in semiconductor physics, with a primary focus on charge carrier transport phenomena. His specific research areas include: (1) regulation of photo-generated carrier transport for photocatalysis and photodetectors; (2) pressure-controlled carrier transport for pressure sensors; (3) charge exchange at solid–liquid interfaces for supercapacitors and photocatalysis; and (4) power management IC design.
