Main Interest

Under the Title of Experimental Solid State Physics, research studies cover semiconductor thin film preparations by using thermal evaporation techniques, besides, electrical, optical and structural characterization of evaporated thin films particularly II-VI and III-VI groups of elements such as CdS and InSe. Moreover, production and optimisation of thin film diode and heterojunction devices by using different noble metals and alloys. Construction of necessary setups for production and characterisation of thin films and also computer controlling of the electrical measurement systems by writing data acquisition programs. In addition to these studies, ceramic temperature sensors and thermal resistors were studied and produced in pellet and/or in thin film forms having negative temperature coefficient (NTC) by using composition of (Co, Mn, Ni, Cu, Fe, etc.) transition metal oxides having cubic spinel metallic structures.
