Tetraguanidinium dichloride-sulphate crystal, [C(NH_2)_3]_4Cl_2SO_4, abbreviated as G_4Cl_2SO_4 was investigated. The vibrational infrared spectra of powdered G_4Cl_2SO_4 crystal in Nujol mull were studied in the wide range of temperature, from 298 K to 377 K. This temperature range contains all the phases in the crystal (named III, II, I on heating, respectively). The temperature changes of wavenumbers,...
In this work TlBiTe_2 were grown by a modified Bridgman technique and examined samples had different lateral dimensions of twins, ranging from 0.1 μm to 1 μm. The average lateral size of the twins seems to affect free carrier concentration and plasma frequency. Infrared spectra were analyzed by two models, the extended Drude model and a generalized empirical model of frequency-dependent damping factor...
