Short Bio

Blanka Magyari-Köpe received her Ph.D. degree in physics from the Royal Institute of Technology, Stockholm, Sweden, in 2003. Since 2006, she has been an engineering Research Associate and from 2011 a Senior Research Engineer in the Department of Electrical Engineering at Stanford University. Prior to this position she was a postdoctoral researcher in the Department of Materials Science and Engineering, University of California, Los Angeles.
Her research interests include adapting and applying high-precision, accurate, and efficient quantum mechanical modeling to real applications. She had been working on the analysis and fundamental understanding of electronic properties of novel and technologically relevant materials, i.e., perovskites, metal alloys, hydrogen storage materials, metal gate/high-k MOS structures and RRAM device materials. Currently, she is involved in projects that involve understanding the RRAM switching mechanism and the role and control of nanointerfaces between metallic, insulating, and semiconducting materials, seeking solutions to design and manipulate them at the atomic level in order to achieve increased performance of electronic devices. Dr. Magyari-Köpe is a member of the American Physical Society (APS), Materials Research Society (MRS), Institute of Electrical and Electronics Engineers (IEEE) and Electrochemical Society (ECS). She received a Swedish Institute Fellowship in 1997. She has given over 24 invited talks and has published more than 50 scientific papers.

Research interest

Main areas of interest include:
  • first principles simulation teqniques to study the structural and electronic implications of interfaces between various materials including ideal (atomically sharp) and with interlayers incorporating defects (vacancies or dopants) in multilayer thin films;
  • the resistive switching properterties of memristor devices in metal-oxide-metal structure, investigating the role of defects in the oxide and of the interfaces with electrodes;
  • oxide breakdown and reliability of the complementary metal-oxide-semiconductor gate structure;
  • uniaxial and biaxial strain effects on semiconductors band structure (Ge);
  • Fermi level unpinning mechanisms by interface doping in metal-semiconductor contacts, NiSi/Si;
