We present a combined experimental and theoretical study of the longitudinal and transverse thermoelectric properties of ferrimagnetic spinels $\mathrm{Cu}{\mathrm{Cr}}_{2}{X}_{4}$ ($X=\mathrm{S}$, Se, Te). The thermoelectric power of all studied pha

Few binary compounds attract as much attention as Bi2Se3. In addition to its use as thermoelectric, it has become one of the prototype 3D topological insulators, and it has been demonstrated that doping in appropriate levels can induce magnetism and

CuInTe2 is a ternary chalcopyrite of the type I–III–VI2 (where I = Cu, Ag; III = Al, Ga, In; and VI = S, Se, Te). This group of materials represents a broad class of semiconductors with potential applications in optoelectronics and photovoltaics

Semiconducting CuFeS2 with a diamond-like structure has been recently studied as a potential candidate for thermoelectric applications. In the present study, Pd substitution for Cu was examined in terms of thermoelectric properties. A series of Pd-do

We performed ambivalent doping study on single crystals of two sets, SnSe1-xAsx and Sn1-xAsxSe, with the aim to explore the interaction of doping species with intrinsic defects. We found that As atoms substitute preferentially for Se atoms in both se

Thermoelectric effects are one of the promising ways to utilize waste heat. Novel approaches have appeared in recent decades aiming to enhance thermoelectric conversion. The theory of energy filtering of free carriers by inclusions is among the lates

The development of intrinsic vacancies in SnSe single crystals was investigated as a function of annealing temperature by means of positron annihilation spectroscopy accompanied by transport measurements. It has been demonstrated that two types of va

Polycrystalline samples with composition Sn1−xTlxSe (for x = 0 to 0.04) have been synthesized from elements of 5 N purity at elevated temperatures. The phase purity of the products was verified by x-ray diffraction analysis. Samples for measurement

The influence of Sn additions was studied in a series of samples of a nominal composition FeSb2Te1−xSnx (x = 0, 0.05, 0.1, 0.15, 0.2). SnTe compound was primarily identified in the matrix compound of the ternary skutterudite structure in the multip
