12040-08-3 Usage
Description
Strontium telluride, with the molecular formula SrTe and a molecular weight of 215.2238 g/mol, is a white, crystalline solid. It has a density of 4.83 g/cm3 and adopts a rock salt structure with octahedral coordination of the Sr2? cation. Its refractive index is 2.408, and it decomposes when heated to 1605 °C. Strontium telluride can be synthesized by heating strontium and tellurium elements together in an inert atmosphere or in a vacuum at specific temperatures. It has the CAS number 12040-08-3.
Usage:
Strontium telluride is not widely used in the industry, and its applications are limited. However, it has been researched for its potential use in the field of semiconductors and optoelectronics. Some of its uses include:
Used in Semiconductor Industry:
Strontium telluride is used as a material in the development of Pb???Sr?Te films, which are prepared by hot-wall epitaxy on BaF?(111) substrates. These films have shown a larger increasing rate of the lattice constant with SrTe content than estimated from Vegard's law.
Used in Optoelectronics:
Strontium telluride has been utilized in the creation of Pb???Sr?Te/PbTe double-heterostructure (DH) and multiple quantum well (MQW) lasers. These lasers were prepared for the first time by hot-wall epitaxy, and pulsed laser operations were obtained at specific temperatures for both DH and MQW lasers. Large output energy shifts due to misfit strain in the active layer were observed.
Check Digit Verification of cas no
The CAS Registry Mumber 12040-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,4 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12040-08:
(7*1)+(6*2)+(5*0)+(4*4)+(3*0)+(2*0)+(1*8)=43
43 % 10 = 3
So 12040-08-3 is a valid CAS Registry Number.
