Title: On the thermopower and thermomagnetic properties of Er{sub x}Sn{sub 1–x}Se solid solutions

Abstract

The Er{sub x}Sn{sub 1–x}Se system is characterized by a significant deviation of the temperature dependence of the differential thermopower from linearity at temperatures below room temperature and a change in the sign of the thermomagnetic coefficient. The deviation of the thermopower of Er{sub x}Sn{sub 1–x}Se samples in the nonequilibrium state from linearity is found to be caused mainly by the entrainment of charge carriers by phonons α{sub ph}. The statistical forces of electronic entrainment, A{sub ph}(ε), are estimated.

  • The effect of doping and degree of compensation on the conductivity activation energy {Delta}E{sub i} in Er{sub x}Sn{sub 1-x}Se has been investigated. The carrier concentration decreases at a low doping level in the case of low and moderate compensations. It is found that, beginning with x {>=} 0.005 at % Er, carriers in the solid solutions under study change sign, depending on the amount of substituted erbium in the SnSe samples that is in equilibrium with the selenium phase. This phenomenon can be explained in terms of the concepts of the self-compensation of donors in the Sn sublattice.
  • The authors followed the change in the electrical properties in the quaternary system Pb-Sn-Te-Se in the section Pb/sub 1-x/Sn/sub x/Se and analyzed the position of the Fermi level as In was introduced into the cubic phase of this solution, bounded by the region x less than or equal to 0.4. Indium was introduced as a cation substitutional impurity in an amount equal to 1 at. %. The Hall coefficient R, the electrical conductivity sigma, and the coefficient of thermo-emf ..cap alpha.. in the interval 77-800/degree/K were measured. An empirical relation describing the behavior of the Fermi level in Pb/sub 1-x/Sn/submore » x/Te/sub 1-y/Se/sub y/ samples doped with In was obtained.« less
  • In this paper the authors have investigated the temperature dependence of the thermal conductivity of PbSe, Pb/sub 0.93/Sn/sub 0.07/Se, and Hg/sub 0.80/Cd/sub 0.20/Te single crystals in the temperature range 200-800/sup 0/K and the concentration dependence of the thermal conductivity of the Pb/sub 1-x/Sn/sub x/Se solid solutions in the range 0.00 less than or equal to x less than or equal to 0.30 at room temperature.
  • In order to determine the predominant intrinsic point defects in Cd /SUB x/ Hg /SUB 1-x/ Se and Zn /SUB x/ Hg /SUB 1-x/ Se solid solutions, the authors study the influence of annealing in mercury and selenium vapor on the carrier concentration and mobility. When the specimens are annealed in selenium vapor the electron concentration at first increases and then becomes constant. A theoretical analysis of the results obtained indicate that selenium vacancies are the predominant point defects in the solutions, and that the process of defect formation itself is quasiepitaxial.
  • The fabrication and study of heterostructures which attempt to combine the advantages of heterojunction lasers and diffusion-fabricated homojunction lasers is reported. Optical and electronic confinement is achieved by composition change during liquid-phase epitaxy.
