Professional Affiliation and Related Activity

    * 1991-1997: visiting scientist of Brookhaven National Laboratory, Professor of research of NY State University at Stony Brook, Polytechnic University, State University at Farmingdale.
    * Founded cross-disciplinary Seminar for technology in Moscow (1977-1990) which attracted many scientists, engineers, architects, and ecologists as a cross-disciplinary brainstorming and training base. Some of participated teams became winner of all-Union competitions in their respective fields.
    * Organized The USA-Russian Seminar for Science, Technology and Defense Conversion. The Seminar assembled 33 top representatives of Russian science and high-tech, 1994, N.Y.
    * Founder and in 1993-97 - Director of International Institute of Materials & Technologies at Polytechnic University, NY
    * Organized the Department of Natural Sciences and Technology in International Summer Young Scientific Camp (Pereslavle Zalesskii, Russia, 1989)
    * Read Lectures on Modern Technology in the range of intensive courses for leading physics and science teachers of the USSR.

Conducted Research On Theoretical

    * statistical micro-kinetic theory of thin films' growth
    * general mathematical theory of poly-nuclear multiphase anisotropic crystallization
    * dynamic contour representation of the growth front of crystals
    * relative shift of thermodynamic equilibrium during heteroepitaxial growth (both theory and experimental proof)
    * diffusion-drift instability in metal-dielectric-semiconductor devices
    * self-focusing and segregation in the incident particles' flux in the field of atomic irregularities of the substrate

Experimental

    * semiconductor, superconductor, magnetic and holographic computer elements
    * epitaxy of germanium, silicon, gallium arsenide, gallium phosphide and mutual hetero-epitaxy of these semiconductors, including first dislocation-free p-n-junctions and super-fast epitaxial growth
    * diffusion-free mechanism of epitaxial growth, in particularly semiconductors
    * diamond-like carbon (from 1962), stabilized diamond-like carbon (from 1978), carbon-carbon and metal-carbon composites of atomic scale (from the middle of 1980s). Extensive applications of stabilized diamond-like carbon films in computers, especially for magnetic disks, in satellite and military electronics, sensors, microelectronic technology, medicine, as well as domestic goods in 1980-1990 in the former USSR and from 1992 in the USA
    * revealed mechanism of electromigration (1978)
    * invented immersion photolithography (1977) and successfully implemented in bubble-magnetic devices (1978, first working magnetic bubble memory in the USSR)
    * physical mechanisms of the semiconductor elements' failures
    * critical parameters of percolation in metal-dielectric diamond-like composites of atomic scale, including quantity proof of the theory in low-stress composites and giant shift of conductivity percolation threshold in high-stress composites
    * synergetic thermal-impact activation of surface reactions (also generalized Arrhenius' equation deduced)
    * atomic - to - mesoscopic scale structural transition in metal carbon diamondlike composites

System Analysis

    * System analysis of physical and technological limits of computer elements. Successful technical forecast allowed the former USSR to cancel superconducting computer projects as early as at the end of 1970-s, while simultaneously limiting gallium arsenide electronics and developing the chip-system concept from that time.
    * Defined the principle limits of the planar technology.
    * Predicted the key role of interconnection technology for future development of IC (in 1972-1978).

Professional Experience

    * 1992-2004 Chief Scientist, Founder and Chairman of Atomic-Scale Design, Incorporated, the Independent Research Laboratory (ASD) + 1992-1995 - Senior scientist of Advanced Refractory Technology, Inc.
    * 1991, January - December. Head of Thin Solid Films Laboratory. Moltech Corporation, at Stony Brook University and Brookhaven National Labs., NY.
    * 1961-1990, December. Head and founder of Laboratory of Solid State Physics and Technology for New Generations of the computer Elements. Institute of Electronic Controlling Machines, Moscow, USSR.
