On the Occasion of Rong's graduation (l-to-r: Wenzhi Lin, Rong Yang, Art, Erdong Lu, Abhijit Chinchore, and KangKang Wang)

My research is concerned with surfaces of semiconductors and metals, particularly focusing on the growth of these materials using molecular beam epitaxy. The analysis techniques of choice in my lab are reflection high energy electron diffraction (RHEED) and scanning tunneling microscopy (STM). RHEED gives information about the growing crystal surface as viewed in reciprocal space during growth; STM gives detailed views of the atomic-scale surface structure. Using these techniques in tandem allows a powerful approach to understanding the relationship between surface structure and growth.

Recently, I am investigating the use of spin-polarized scanning tunneling microscopy in studying the magnetic structure of surfaces down to the atomic scale.

ATOMS PROGRAM

(Advanced Techniques of Microscopic Science)

With funding provided by the National Science Foundation (NSF), a program for K-12 teachers and their students, called ATOMS, was established.  The primary goal of ATOMS is to increase science and technology opportunities for Southeastern Ohio students by exposing them to Nobel Prize-winning technology.  This is achieved by making available to local students and their teachers a scanning tunneling microscope (STM).  The STM is capable of imaging surfaces with atomic resolution.
