Rate My Professor Wei Zhang

Professor Wei Zhang is the Professor of Nanoelectronics in the School of Engineering's Department of Electrical and Electronic Engineering at Liverpool John Moores University (LJMU). He leads the Microelectronics Research Group and the memory device research area, having supervised fourteen PhD students. Zhang obtained his PhD degree from LJMU in 2003 and has advanced through the ranks at the university, previously serving as Reader in Microelectronics.

Zhang's research specializations encompass microelectronics, with a focus on emerging non-volatile memory technologies including resistive random-access memory (RRAM), ovonic threshold switching (OTS) selectors using materials like GexSe1-x, ferroelectric resistance switching, and memristive devices for neuromorphic in-memory computing and neural networks. He has made significant contributions to understanding switching mechanisms, endurance enhancement via novel refreshing schemes, nitrogen doping effects in ALD Ta2O5 for multilevel cells, and non-idealities in memristor arrays addressed by committee machines. His influential publications include "Recommended methods to study resistive switching devices" (Advanced Electronic Materials, 2019; 776 citations), "Giant ferroelectric resistance switching controlled by a modulatory terminal for low‐power neuromorphic in‐memory computing" (Advanced Materials, 2021; 143 citations), "Committee machines—a universal method to deal with non-idealities in memristor-based neural networks" (Nature Communications, 2020; 111 citations), "The role of nitrogen doping in ALD Ta2O5 and its influence on multilevel cell switching in RRAM" (Applied Physics Letters, 2017; 93 citations), "Tailoring the synaptic properties of a-IGZO memristors for artificial deep neural networks" (APL Materials, 2022; 59 citations), "Two-Pulse – : A New Method for Characterizing Electron Traps in the Bulk of Dielectric Stacks" (IEEE Electron Device Letters, 2008; 66 citations), and "A single pulse charge pumping technique for fast measurements of interface states" (IEEE Transactions on Electron Devices, 2011; 55 citations). Zhang has delivered invited seminars, such as on chalcogenide materials based threshold switching mechanisms and emerging memory devices at institutions including Loughborough University and the University of Glasgow. His work drives advancements in low-power, high-speed computing hardware.
