Peng Xiong is a Professor in the Department of Physics at Florida State University, with a research focus on electron and spin transport in low-dimensional quantum materials. He is affiliated with the Integrative NanoScience Institute (INSI) and has made significant contributions to mesoscale physics, spintronics, and organic/solid-state hybrid systems.
- B.S. in Physics (1987, University of Science and Technology of China)
- Ph.D. in Physics (1993, Brown University)
- Postdoctoral Fellowship (1993-1997, University of California at San Diego)
Research Interests:
Mesoscale Physics: Quantum phase transitions and fluctuation effects in 2D and 1D systems, semiconductor nanowires, carbon nanotubes, and nano-magnetism. Spintronics: Spin-polarized transport in hybrid structures (ferromagnet/normal metal, ferromagnet/superconductor, ferromagnet/semiconductor), magnetic semiconductors, and spin injection/detection. Organic/Solid-State Hybrids: Nanoscale biosensors utilizing magnetic and electrical principles, bio-mechanical devices, organic/solid interfaces, and template-directed nanostructure self-assembly.
Publication Trends:
His recent work spans superconducting fluctuations in ultrathin films, chirality-induced spin transport in semiconductors, interplay between structural chirality and spin-orbital effects, ion migration dynamics in 1D hybrids, quantum interference in nanowire loops, and modulation of nanomaterial properties through surface defect engineering. These studies often combine material synthesis, nanofabrication, cryogenic transport, and tunneling measurements.
