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. Increase in size of twins affects the electronic properties and hence plasma reflectivity and free carrier concentration of TlBiTe_2.
