Albert Davydov (Fed)

Albert Davydov is a leader of Functional Nanostructured Materials Group. The group of 12 staff scientists and 7 guest researchers develops measurement methods, models, data, standards, and science for the electrical, chemical, and magnetic properties of nanostructured inorganic materials, including metals and semiconductors, as related to their microstructure and processing. Three active projects in the group are focusing on materials and processes for  advanced electronics, magnetics, energy and catalysis: 1) Electrochemical Processes (POC: Tom Moffat), 2) Metrology of Magnetic Materials (POC: Cindi Dennis), and 3) Low-dimensional Materials and Magnetic Thin Films for Advanced Microelectronics (POC: Albert Davydov). 

Research Opportunities with the Group: National Research Council Postdoctoral Fellowship (open to U.S. citizens) - please contact above POCs if you're interested in applying.

 

Short Bio: Albert Davydov started his career as an Assistant Professor at the Department of Chemistry at MSU (1989-1993), then as a Research Scientist at the University of Florida (1993-1997), followed by NIST Research Associate position with the University of Maryland (1997-2005). He joined NIST as a staff scientist in 2005. He has extensive experience and publication record (~150 publications in peer-reviewed journals, 5 patents) related to fabrication, processing and microstructural characterization of a wide range of electronic materials including semiconductors, 2D and quantum materials. His expertise also includes thermodynamic modeling and experimental study of phase diagrams for metal and semiconductor material systems.

He serves as a Head of the Semiconductor Task Group for the International Centre for Diffraction Data (ICDD), member of Advisory Board with the Applied Physics Review journal, member of the Science Advisory Board with the nanoelectronics COmputing REsearch (nCORE) program at SRC, co-Chair of the Reference Materials Task Group at ASTM Subcommittee on Compound Semiconductors, member of Technical Committee 229 (Nanotehcnology) at International Organization for Standardization, and co-Chair of SPIE Optics & Photonics Conference on Low-dimensional Materials and Devices.

He has been mentoring and co-advising for M.Sc. and Ph.D. students from the DC metropolitan area universities and for NRC postdocs at NIST.

Research interests:
1) Bulk crystal and thin film growth of compound semiconductors, 2D and quantum materials, including transition metal dichalcogenides, Group IIIA-VA chalcogenides

2) Fabrication, processing and characterization of semiconductor nanowires: Si, GaN, SiC, ZnO

3) Thermodynamic assessment of phase diagrams for metal/semiconductor systems: Ga-N, Co-Mo etc.
