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 ,
Selfportrait at 6th wedding anniversary 1988 and is today at the Paula Modersohn-Becker Museum in Bremen, the first museum devoted to a female artist. Selfportrait at 6th wedding anniversary Self-Portrait on the sixth anniversary of marriage was painted in Paris. She had moved from Worpswede near Bremen in Germany in February 1906.
