Divine P Kumah

Kumah

Associate Professor of Physics

Divine Kumah received his B.S in Physics from Southern University, Baton Rouge, and a Ph.D in Applied Physics from the University of Michigan in 2009. His postdoctoral research work was performed at the Center for Research in Interface and Surface Phenomena at Yale University. His research interests are in experimental condensed matter physics and are aimed at understanding the novel electronic and magnetic properties which emerge at the interfaces between crystalline materials.
The Kumah Research Lab uses state of the art atomic layer-by-layer deposition techniques including molecular beam epitaxy to fabricate thin crystalline oxide films. The group is focused on understanding how atomic-scale structural distortions at interfaces can be manipulated to induce novel electronic and magnetic phenomena and the development of pathways for harnessing these unique functionalities for electronic and energy applications. Tools used by the group include atomic force microscopy, electron diffraction and synchrotron-based x-ray spectroscopy and diffraction.
