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 ,
Wedding dress of Princess Mary of Teck (although "The Times" reported there was none) and the veil of her mother's which she wore was also made of Honiton lace, fastened by diamond pins given as a gift from Queen Victoria. Matching the orange blossom elements to the dress, small wreaths were placed all the way around the bust and on the hair. Princess Mary completed the wedding outfit with a diamond tiara from Queen Victoria; diamond rivière necklace from the Prince and Princess of Wales and diamond earrings and anchor brooch, a wedding gift from Prince George. Out of all of the wedding toilette, the veil was
