MBE-by-Design

Sub-group leader Dr. Patrick Vogt

The 'MBE-by-Design' group (led by Dr. Patrick Vogt) focuses on the discovery and identification of novel reaction mechanisms and new compound formations in MBE. The research goal is the development of new MBE variants and the growth of functional materials with properties superior to any known. This is achieved by investigating, understanding, and modeling the reaction kinetics and thermodynamics of thin films grown by oxide and nitride MBE.  
 
The group collaborates with Cornell University (NY, USA), Penn State University (PA, USA), and Max-Planck-Institut für Eisenforschung (MPIE), for the experimental and theoretical exploration in new directions in synthesis-science.   

Short Bio: 

Patrick Vogt received his Ph.D. (with distinction) from the Paul Drude Institute, Berlin. He subsequently joined the groups of Prof. James S. Speck at UC Santa Barbara (UCSB) and Prof. Darrell G. Schlom at Cornell University where he invented new directions in MBE growth. He received the Lise Meitner Prize (Humboldt University) for his studies on oxide MBE growth kinetics and thermodynamics, has published multiple papers on new MBE growth mechanisms as well as MBE variants and holds a US patent on the recently invented suboxide MBE (S-MBE) technique.
