Temperature Dependence of the Reﬂection Spectra of the Plasma CrystalBi0,6Sb1,4T e3 in the Temperature Range of 78 K - 292 K
During the studies of the optical properties of solid solutions of Bi2T e3-Sb2T e3 the changes in the state of the electronic system by varying the temperature and the ratio of components of Bi2T e3 and Sb2T e3 were considered. It was found that when the content of75 per cent in theSb2T3 solid solution of a convergence of energy of plasma oscillations offree charge carriers and energy inter-band transitions forming the fundamental absorptionedge. Reducing the temperature of the crystalBi0,6Sb1,4T e3 from 300 to 78 K, it is possibleto observe a smooth shift of the plasma edge to the edge of the fundamental absorption andreﬂection spectra of the strain caused by amplifying the electron-plasmon interaction.
