Tin telluride wavelength range. The alloyed material has been used in mid- IR photodetectors and thermoelectric generator. Tin telluride Tin telluride is a compound of tin and tellurium (SnTe); is a IV-VI narrow band gap semiconductor and has direct band gap of 0.18 eV. It is often alloyed with lead to make lead tin telluride, which is used as an infrared detector material. Tin telluride normally forms p-type semiconductor (Extrinsic semiconductor) due to tin vacancies and is a low temperature superconductor. SnTe exists in 3 crystal phases. At Low temperatures, where the concentration of hole carriers is less than 1.5x10 cm ,
EMLL 15th Anniversary Show noticed by the referee. Records indicated that there were two preliminary matches on the September 24th show, but records of neither the participants nor the actual results of these matches have been confirmed. The third match of the night featured Rito Romero wrestling against Black Shadow, but no record of who won is found. Likewise the results of the fourth match between Gory Guerrero and Bobby Bonales are also undocumented. In the main event NWA World Middleweight Champion Tarzán López successfully defended the championship against the challenger Harry Fields in a Best two-out-of three falls match.
