Abstract : The switching phenomenon is one of the numerous interesting effects arising in strong electric fields. This phenomenon has been observed in a great number of crystalline, amorphous, and liquid semiconductors. At present the nature of the switching phenomenon is not yet clear and the experimental data available has not been explained unambiguously. Conflicting explanations of the experimental data are due mainly to the complex nature of the switching phenomenon, consisting of a series of independent stage during which different mechanisms can act. That is why an investigation of this phenomenon in single crystal semiconductors is of special practical interest, and can be useful for the development of the switching theory. Switching and memory effects in the electronic state are of recent interest due to possible technological applications such as switching and memory devices, oscillators, and thermistors, etc. In fact very little is known about the physical properties of thallium indium ditelluride. The interest in this material is stimulated not only by their fundamental properties, but also by possible practical applications. The particular interest shown in switching studies of the P-type TLInTe2 compound is associated with the possibility of using it as effective switching and memory elements in electronic devices. In this project we shall discuss the switching phenomenon, and shall try to elucidate the conduction mechanism of TlInTe2 single crystals. Also we shall study the effect of ambient conditions, such as temperature, light illumination as well as the active thickness of the sample on the behavior of this phenomenon and the parameters of this phenomenon. By this investigation (Crystal growth and switching effect study), we can find out the suitable field of practical application.
