Degrees:
Ph.D.
(Condensed Matter Physics):
at
Affiliations after Ph.D.
Graduation:
(1981),
of the physics dept. of BGU. Retired in september 2009.
Subjects of Research: (in a backward order, ending with Ph.D. thesis).
1. The HTSC Cuprates. Their Superconductivity and Pseudogap states.
2. The
Generalized Hartree-Fock Theory of Metals in the
includes effects of disorder (A25).
3. An analysis of oxide superconductors by means of the Generalized Hartree-Fock Theory of Superconductivity
(A15-A17, A20, A22, A24). This work includes the generalization of the Eliashberg equations to non-magnetic
HTSC.
4. The conductivity and semiconductivity of organic conductors (B4, A19, A21).
5. Non-phononic mechanism of superconductivity (A8, A14). A fundamental principle of the nature of solid
Materials was proved. It states that a non-phononic screening cannot be of negative sign at low energies,
otherwise, it must result in lattice instability.
6. The surface structure of cubic
SiC in various phases (A12, A13, C3). This Work is
the first serious
study of the structure of the
(100) surface of cubic SiC. It discovered three Si-rich
surface phases,
and one C-rich phase.
7.
High resolution EELS study of a single crystal cubic SiC (A11, C3).
8. The CVV Auger line shape of diamond,
polyethylene and single crystal cubic SiC (A10, A12, A13).
9. Sputtered Hydrogenated a-Si (A7, C2).
10. The Superconductive Tc , derived from the strong-coupling theory (A6).
11. Superconductive transition of V3Si A15 crystals (A5).
12.Electron tunneling in superconducting granular and crystalline Al (A2, B1). This is my Ph.D. thesis work,
which was supervised by G. Deutscher.It makes use of the "phonon induced " structure in the tunneling
density of states to invert thegap equation and obtain a2F and m*. By applyin this technique to Al, its limit
was pushed down to the weakest coupling superconductor it has ever been applied to.
Skills and Techniques:
1. Electronics.
Experience in electronics was gained during military service as an electronic technician, and was further
developed and modernized through my career. I have regularly designed the non-standard circuitry which was
needed for my measurements.
2. Vacuum
Wide
experience with various vacuum systems, including oil systems and UHV
systems (with ion
pumping or cryogenic pumping).
Gas analysis in various systems.
3. Cryogenics
Many years of experience in low temperature experiments. Design and operation of a 3He refrigeration
system and a few 4He systems.
4. Film Deposition
Many years of working experience with various thin film deposition techniques, such as thermal evaporation,
e-gun, sputtering and casting thin films of polymers from solutions.
5. Film
Characterization
Characterization techniques such as conductivity vs. temperature, photoconductivity and electron tunneling,
were regularly employed by myself. Some familiarity with electron microscopy.
6. Surface Analysis
Surface preparation and treatment, including surface activations
by molecular beams.
Auger Electron Spectroscopy, Low Energy Electron Diffraction, and Work Function measurements.
Experience with the state of the art
(5mV resolution ) Electron Energy Loss Spectroscopy.
7. Preparation of Oxide Superconductors.
8. Theory
Even though "experimentally Oriented", I have regularly tried to catch up with advanced theories, and have
published many Theoretical papers. Actually, since 1988 most of my research work is theoretical, due to a lack of
experimental facilities. I conside the ability of a physicist to "interact"with the theoretical and experimental aspects
of his subject an essential requirement.
Teaching Employment
I taught for nine years in student laboratories of all levels. I also gave a full year course of basic electronics
at the
school of engineering of
During 1992-1996, I was responsible for Physics demonstrations in all classes of physics. During 1997-2001, I
have been responsible for designing and setting-up experiments, and for writing the instructions, for theadvanced
student lab. in the Physics Dept. of B.G.U. Since March 2002 I am again in the Physics Demonstration Lab.
Activity in workers union
affairs
During 1998-2000 I served as the union representative of the technical
staff at
Awards and Honors.
1976:
Landau Award at
1982-1984: NRC Senior Research Associateship Award.
1996: My biography is published in the 14th edition of Marquis Who's Who in the World.
Art Activity
I write poems in Hebrew, paint, and sculpture. Some of my art works are presented in my site at
