Master Degree student at King Khalid University, Department of Physics, Maha Jaber Al Saleh has presented a new study from optical conductivity of single crystals of TlInS2. The study aimed to identify the optical characteristics of the crystals and to promote its use in many applications.

Al-Saleh explained that the compound thallium indium binary sulfide single crystallization received a great deal of attention due to its optical and electrical characteristics. She reported, "I made this research to shed light on the possibility of using it in optoelectronic applications, if we realize that this semiconductor compound is interesting to study because it will give the possibility to be used in the field of technological applications." She further showed that, according to previous studies, the information on the optical conductivity feature of this compound is simple. She emphasized that through this study, it became possible to identify most of the optical features of the compound thallium indium binary sulfide single crystallization, saying "This study reinforces the usage of the compound in many critical applications, such as solar cells - optical torches – Data storing. In addition, these materials have the ability to generate electrical energy from the sun rays).
