Peng Zhang’s research interests are in theory and modeling of nanoelectronics, electromagnetic fields and waves, plasmas, and accelerator technology. He has worked on electrical contacts, thin films, classical, ballistic, and quantum diodes, space-charge-limited current flows, beam-circuit interaction, microwave absorption on rough surfaces, multipactor and breakdown, slow wave structures, z-pinches, laser-plasma interaction, and more recently on vacuum nano devices, quantum tunneling plasmonic junctions, ultrafast photoemission, and novel miniaturized light sources. Prior to joining MSU, he was an Assistant Research Scientist at the University of Michigan.
