Shibin Krishna, Ph.D.

Alumni and Former Staff

​​​Postdoctoral Fellow in Fatayer Group

Research Interests

Shibin's research focuses on the 2-dimensional (2D) material growth by molecular beam epitaxy and its in-situ characterization by scanning tunneling microscopy and X-ray photoelectron spectroscopy. He is also interested in studying surface detects, atomic reconstructions and manipulations of 2D materials.
