Title A name given to the resource Gamma irradiation effects in InBi0.8Te0.2 crystals grown by horizontal directional freezing Subject The topic of the resource Crystal growth; Dielectric properties; Hardness; Irradiation; Optical properties Description An account of the resource The high-energy gamma-ray irradiation treatment using Co-60 isotope offers the possibility of engineering mechanical and optoelectronic properties of InBi0.8Te0.2 crystals. Tellurium-doped indium bismuthide (InBi) crystals were prepared by horizontal directional freezing technique. Dose-dependent modifications in structure, composition and surface topographical features have been analyzed by X-ray powder diffraction, X-ray energy-dispersive analysis, transmission electron and atomic force microscopy, respectively. Dielectric constant and dielectric loss were found to increase with the cumulative dose of radiation, and a shift in the ferroelectric transition temperature (T0c0) from 405 to 410 K was observed for 25 kGy. Upon irradiation, there is an enhancement in microhardness (H0V0), yield stress (sigma; 0y0) and stiffness constant (C0110). The optical transmittance was decreased by 12.45%, resulting in a reduction in the optical band gap from 0.210 eV to 0.198 eV. These results indicate the suitability of InBi00.80Sb00.20 crystals for low-wavelength infrared applications. The Chinese Society for Metals and Springer-Verlag Berlin Heidelberg 2015.
