Professional experience
Materials Scientist Brookhaven National Laboratory, Upton, NY 2006 - present
Principal Investigator of a research program aimed to find new ways of radically improving structure quality of thick epitaxial layers of complex oxides.
- Discovered isotropic transport in strained layers of YBCO oxide material (in collaboration with Leonardo Civale of Los Alamos Lab).
- The program was rated 3rd out of 10 by U.S. Department of Energy review panel.
- Implemented a new method for rapid structure and texture diagnostics of thick coatings, which enabled fast assessment of texture quality and nucleation efficiency. Tools used: Raman Microscope (JY Horiba), Buehler polisher.
Associate Scientist Brookhaven National Laboratory, Upton, NY 2003 - 2006
Co-investigator of a program on study of conversion thermodynamics high-performance complex oxide layers on large area substrates ($400 K funded by DOE)
- Established the fundamental dependence between the nucleation rate and the processing conditions.
- Identified accumulation of secondary phases within the new phase grains as the major source of structure degradation. Tools used: X-ray diffraction analysis (Phillips diffractometer) and site-sensitive transmission electron microscopy (JEOL 3000).
- Initiated licensing of technology for sub-atmospheric processing of large-area epitaxial layers (U.S. patent # 6,794,339), established royalty account. The technology also used at Oak Ridge National Lab (U.S.), ISTEC (Japan).
Assistant Scientist Brookhaven National Laboratory, Upton, NY 2001 - 2003
As a part applied materials group investigated new ways of ultra-fast processing of epitaxial coatings.
- Clarified critical details of the nucleation mechanism which enabled raising the nucleation rate of epitaxial layers on single-crystalline substrates. Tools used: electron microscopy (JEOL 3000, with Dr. Wu) and X-ray diffraction (Hueber goniometer).
- Developed a new technology for cost-effective deposition of fluorinated films by electrostatically assisted thermal spray with subsequent fluorination using C2H4F2 gas, patent application filed.
- Invented and implemented sub-atmospheric reactor for processing of high volume of superconducting tape (with Dr. Harold Wiesmann),U.S. patent # 6,794,339. The invention enabled to increase the production rate by 500% and reduce carrier gas consumption by a factor of 100
Research Associate Brookhaven National Laboratory, Upton, NY 1997 - 2001
Post-doctoral research under cooperative research agreement with “Oxford Superconductor Inc.” on evaluation of applicability of a new technology for high-rate growth of thick epitaxial films.
- Set-up high-rate e-beam gun evaporation system for deposition of thick precursor layers. Achieved 0.2 layer composition uniformity over 10 cm area at 3 micron the film thickness and the deposition rate 20 nm-s.
- Designed and implemented a lab-scale gas flow reactor with an electronic processing atmosphere control (MSC gas flow controls, LabView software) with the atmosphere composition accuracy 0.1 ppm (residual gas analysis using Dytek quadrupole mass-spectrometer).
- Implemented original and rapid method for in-situ reaction rate measurement during the conversion reaction, now used in ISTEC (Japan).
- Using the reaction rate information, performed thermodynamic analysis of the growth kinetics (MatLab-FemLab package), which identified the product gas removal as the growth limiting step. This result led to invention of the sub-atmospheric reactor.
