Miniature High-Sensitivity Sensors For Medical Devices For Poor Citizens
Abstract
Multicomponent anisotropic semiconductors I-III-VI2 have ample opportunities for practical application in optoelectronics. The ternary compound CuInSe2 is used as an absorbing layer in high-efficiency solar cells. With a band gap Eg ≈ 1.05 eV, it is characterized by an exceptionally high absorption coefficient (α_L ≥ 105 cm–1). The basis for many photoconverters are heterojunctions created between CdS and CuInSe2, but the metal–CuInSe2 structure can also be a simple and cheap alternative. The study of concentration dependencies of resistivity and strain-sensitivity coefficients of single crystals of TlInSe2-CuInSe2 solutions grown by the Bridgman-Stockbarger method revealed important parameters of semiconductor materials based on theoretical calculations and experimental studies of concentration dependencies of specific conductivity both in the absence and presence of one-sided deformation along the tetragonal axis [001]. The dependence of the sensitivity factor of strain-sensitive elements of Tl1-xCuxInSe2 (0 ≤ X ≤ 0.025) alloys along the axis [001] on the concentration of Cu was determined, and it was found that the tensoresistive properties of these crystals remain stable under repeated exposure to external physical factors.
