Solid State and Semiconductors Physics
In 1976, the Higher mathematics and Physics departments were established on the basis of the Higher Mathematics and physics department, and until 1976-1990 prof. E.M. Gojayev led this department. In 1990-1996, associate professor E.H. Mammadov  and in 1996-2001, prof. M.M. Zarbaliyev led the department.
In 2002, General physics and Theoretical physics departments were established on the basis of physics department; in 2004 departments of Solid state electronics and Semiconductors were created. According to the decision of Scientific Board of Sumgayit State University dated 30.03.2017 those two departments were united and called department of Solid State and Semiconductor physics.

Main scientific directions:
1. Development of obtaining, synthesis and cultivation of monocrystals technology of complex semiconductor compound with rare earth element and solid solutions; identification of their application perspectives.
2. Obtaining of compounds applied in microelectronics, their contacts, investigation of their physical-chemical properties and application.
3. High energy physics. Determination of the mass at the arbitrary value of the hyperfunctions of particles.
Important scientific results obtained:
1. TlIn1-xYbxTe2¬ (0≤x≤0.10) solid solutions were synthesized and their single crystals were grown.
2. It was determined that TlIn1-xYbxTe2¬ solid solutions have hole permeability in the form of a strongly torn hole gas in the studied temperature range (80÷1000K). Specific conductivity is observed at temperatures T≥650K.
3. The nature of the temperature dependence of and is explained by the presence of two types of charge carriers in the studied material.
4. Starting from x=0.05, when passing from TlInTe2 to solid solutions obtained on its basis, it was concluded that the strong change of the temperature dependence of is due to the transition from a semiconductor to a narrowband semiconductor.
5. The proposed semiconductor model with one (holes) and two (electrons and holes) charge carriers, taking into account the scattering of charge carriers from ion centers, acoustic and optical phonons, defects and explains thermoelectric properties well.
7. Electrical conductivity and Hall effect were studied in p-CdxHg1-xTe (0.27  x  0.30) single crystals in the temperature range of 77 - 300 К. The width of the forbidden zone Еg and the concentration of additive levels and the activation energy Еа were determined from the dependences of (Т) and Rx(Т) for the studied compositions. It was determined that the dominant scattering mechanism in the considered temperature range is Coulomb scattering from the Coulomb potential (from ionized additives and holes), and the mobility of charge carriers increases with increasing temperature.
8. As the size of nanoparticles decreases, the width of the forbidden band increases from Eg=2.02 eV to Eg=2.18 eV. The quantum effect becomes more pronounced when the size of the GaSe nanostructure becomes smaller than D=10 nm. The temperature dependence of the electrical conductivity of GaSe nanoparticle in the temperature range of 200 - 300K is exponential.
The activation energy of charge carriers was calculated from the inclination of log =f (1/T) dependence, Еа= 0.32 eV.
9. LED layers with InGaN/GaN multilayer quantum holes were grown by Metal Organic Gas Phase Epitaxy method, and blue LED chips were obtained from them. As a result of the electroluminescence study of the received LED chips (x=0.156:y=0.216), color coordinates and dominant wavelength λd=451nm were determined.
