Personal:                Married with three children

Current address:     Work: Physics Department, Ben-Gurion Univesity,Beer-Sheva, Israel

E-Mail address:      mdayan@bgu.ac.il

 

Degrees:        

            Ph.D. (Condensed Matter Physics): Tel-Aviv University, Nov. 1976. B.Sc. and M.Sc. in Physics, received

at Tel-Aviv University (in 1968 and 1971).

 

Affiliations after Ph.D. Graduation:

            University of Minnesota (1977-1978), Tel-Aviv University (1979-1980), Case Western Reserve University

(1981), NASA Lewis Research Center (1982-1985), Technion (1986-1988). Since 1988 I am in the technical staff

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 Normal and in the Superconducting States (A23). This

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 Tel-Aviv University, and a course of solid-state physics at Ben-Gurion University.

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 Ben-Gurion University.

 

Awards and Honors. 

            1976: Landau Award at Tel-Aviv University.

            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
