Biography

Xihong Peng joined Arizona State University, Polytechnic campus, as an assistant professor in the program of chemistry, physics, and applied mathematics in 2008 and was promoted to associate professor in 2014. She received her doctorate in physics from Rensselaer Polytechnic Institute, Troy, New York, in 2007, and her  bachelor's degree in physics from Beijing Normal University, China, in 2000. She was a visiting assistant professor at Skidmore College, Saratoga Springs, New York for the 2007-2008 academic year before joining ASU.

Peng's research interests are to explore novel materials and seek their application in nanoelectronics and renewable energies, as well as to gain a fundamental understanding of the materials’ properties at the atomic level.

Research Interests

Peng's primary field of expertise is first-principles calculations of the electronic structures of a variety of materials and systems. The advantage of first-principles calculations is that the key properties and behaviors of physical systems, including energies, structural and electronic properties, can be readily predicted using Schrodingers Equation from Quantum Mechanics without having to rely on fitting parameters. First-principles calculations are also applicable to solving problems across various fields, ranging from physics and chemistry to biology and material sciences. They are playing an essential role in modern scientific research and explorations. 

Peng's research interests are to explore novel materials and seek their application in nanoelectronics and renewable energies, as well as to gain a fundamental understanding of the materials properties at the atomic level.

Key research interests: 

  • First-principle density-functional theory calculations of electronic properties, strain effect and photo-chemical characteristics of group IV, V, III-V, II-VI nanowires, carbon nanotubes, graphene nanoribbons and phosphorene for potential application in nano-electronic devices.
  • Investigation of novel materials for photocatalysts and high capacity Li-ion battery electrodes through theoretical calculations.
  • Investigation of physical and photo-chemical properties of transition metal oxide catalysts via density-functional theory.
