Tin telluride 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 , Tin Telluride exists in rhombohedral phase also known as α-SnTe. At room temperature and atmospheric
Puyo Puyo! 15th Anniversary from the Madou series, who serve as boss characters in the story modes. As "Puyo Puyo! 15th Anniversary" was created to commemorate the fifteenth anniversary of Puyo Puyo, it includes most of the "Fever" characters plus six of the characters from the "Madou" series; they are said to have fallen from the sky into Primp Town, the primary setting of the Fever series games. There are a total of twenty-two characters in this game. 15th Anniversary has a slew of new modes, and also includes modes that emulate the original "Puyo Puyo", "Puyo Puyo Tsu" and "Puyo Pop Fever".
