Article type
Annotation In semiconductor materials Bi2Te3 — Sb2Te3, in which the width of the forbidden band is comparable to the plasmon energy Eg ps Ep, an anomalous increase in the electrical conductivity is observed in the low-temperature region. The change in the permittivity and the effective mass of free charge carriers, which occurs at higher temperatures, leads to a decrease in the plasmon energy, a decrease in the intensity of plasmon generation, a concentration of free charge carriers, and electrical conductivity.
Key words semiconductor materials Bi2Tes~Sb2Tes, electrical conductivity, concentration of free charge carriers
