The particular interest shown in switching studies of p-type TlGaS2 compound is associated with the possibility of its uses as an effective switching and memory elements in electronic devices. The switching effect observed in such crystal shows a memory character. Using a crystal holder and cryostat we measured the switching phenomenon at different ambient conditions such as temperature, light illumination as well as sample thickness. Pronounced parameters for switching for sample of thickness 0.17 cm were determined from the experimental data such as threshold voltage Vth = 400 V, threshold current Ith = 37 μA, holding voltage Vh = 350 V, holding current Ih = 42.3 × 10-4 A, threshold power Pth = 1.48 × 10-2 W, threshold field E th = 196.429 V/cm as well as the ratio between the resistance in the off state ROFF to the resistance in the conducting state R ON as 130.253. The factors affecting these parameters have also been investigated.  ISSN : 0169-4332  Journal Name : Applied Surface Science  Volume : 257  Issue Number : 8  Publishing Year : 1432 AH 2011 AD  Article Type : Article  Added Date : Monday, February 6, 2012  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email أحمد عبدالله الغامدي Al-Ghamdi, Ahmad A Researcher Doctorate AGAMDI@kau.edu.sa نجاة توفيق عباس Abbas, Nagat T Researcher Doctorate Dr.Nagat@hotmail.com فاطمة سالم باهبري Bahabri, Fatima S Researcher Doctorate fbahabri@kau.edu.sa رقية حسين العريني Al-orainy, Roqaya H Researcher Doctorate r-aloraina@hotmail.com صباح عيد القرني Algarni, Sabah Eid Researcher Doctorate sabdulah@kau.edu.sa Files File Name Type Description  32185.pdf pdf Abstract Back To Researches Page
