Physical Experiment II

Interests

· We focus on MBE growth of low dimensional materials, such as high-temperature superconductors and topological insulators. In-situ STM/STS and ARPES measurements are then carried out to characterize the novel electronic properties of the materials both in real and momentum space. Our ultimate goal is to understand the mystery of high-Tc superconductivity and pursue superconductors with higer transition temperatures (up to room temperature if possible:).
