Biographical Sketch and Research Highlights

Lei Xiaolin was Born in November 27, 1938 in Guilin, Guangxi Province, China and graduated from the Department of Physics, Peking University in 1963. After teaching at Shandong University from 1963 to 1976, he joined the research staff of Shanghai Institute of Metallurgy, Chinese Academy of Sciences (CAS) in late 1978. He was a visiting scientist (1983-1984) at University of Houston, a visiting associated professor (1984-1985) at City College of City University of New York, and a visiting professor (1985-1987) at Stevens Institute of Technology, USA. He was a research professor (1986-2000) at Shanghai Institute of Metallurgy, CAS and elected the academician of the Chinese Academy of Sciences in 1997. He is currently a professor of Shanghai Jiao Tong University.

Jointly with Prof. Wu Hang-sheng in early 1960s, he proposed the idea of size nonlocality in film superconductors and established the minus 3/2 power law for the thickness-dependence of the critical field in superconducting thin films. During late 1970s and early 1980s, he investigated on the convergence of the superconducting critical temperature series, the conductance of A15 compounds, ferromagnetic materials and highly resistant alloys, and the thermodynamics and optics of complex superconduting systems, developing the S-scattering model for the resistivity of disorder crystal alloys and the gap-excitation model for charge-density-wave superconductors. Jointly with Prof. C.S. Ting in mid-1980s, he established the balance-equation theory for hot-electron transport in semiconductors, which, known as Lei-Ting theory, has since been widely used in theoretical calculations and experimental analyses for nonlinear transport in various bulk and low-dimensional semiconductors.

In early 1990s, he proposed a Bragg-scattering model for electrons moving in a periodic potential and derived transport equations for systems with arbitrary energy spectra in the presence of both an electric field and a crossed magnetic field. In late 1990s, he brought forth a set of balance equations for terahertz-field-driven dynamics, facilitating the evaluation of major transport and optical properties while covering all the multiphoton processes.

In 2003, he proposed a photon-assisted electron transition model and developed basic equations for radiation driven magnetotransport in semiconductors. This theory not only successfully explained the experimental discoveries on microwave-induced magnetoresistance oscillations in high-mobility two-dimensional electron systems but also disclosed many other details of this fascinating phenomenon. X. L. Lei has been the leading author of more than 160 and the coauthor of more than 130 academic papers published in major journals in the field of condensed matter physics. He was the author of the monograph “Balance equation approach to electronic transport in semiconductors”. He was awarded a First-Class CAS Prize of Natural Sciences (1994), a Second-Class China National Prize of Natural Sciences (1995), and a Ho-Leung-Ho-Lee Prize for Science and Technology Progress in Physics (2006).
