We present a study of magnetic and magneto-optical properties of CdxTe12x-MnTe superlattices up to the room temperature. A comparison of low-temperature exciton Zeeman effect and the measurements of the magnetization performed by superconducting quantum interface device magnetometer shows a perfect agreement with a model description, thus allowing for determination of Mn content profiles width ...

Understanding the degradation mechanisms of organic photovoltaics is particularly important, as they tend to degrade faster than their inorganic counterparts, such as silicon and cadmium telluride. An overview is provided here of the main degradation mechanisms that researchers have identified so far that cause extrinsic degradation from oxygen and water, intrinsic degradation in the dark, and ...

This paper presents the results of the synthesis and evaluation of thick thermoelectric films that may be used for such applications as thermoelectric power generators. Two types of electrochemical deposition methods, constant and pulsed deposition with improved techniques for both N-type bismuth telluride (Bi₂Te₃) and P-type antimony telluride (Sb₂Te₃), are performed and compared. As a result,...

High performance semiconducting thin films enable the implementation of thermoelectric generators as energy harvesters for wearable applications. The optimization material properties is critical in such applications, restrictions introduced by substrates on deposition temperature and active layer size, impose fundamental limitations performance. Here we present sputtered bismuth telluride, BiTe...

Pampaloite AuSbTe, a rare gold-antimony telluride that was first described in 2019 from the Pampalo gold mine, Finland, found samples large Svetlinsk gold-telluride deposit, South Urals, Russia. Optical microscopy, scanning electron microprobe analysis, reflectance measurements, backscatter diffraction and Raman spectroscopy were used to study eight grains of pampaloite. forms inclusions (5–30 ...

The decoupling and enhancement of both Seebeck coefficient and electrical conductivity were achieved by constructing the c-axis preferentially oriented nanoscale Sb(2)Te(3) film on monolayer graphene. The external graphene layer provided a highway for charge carriers, which were stored in the thicker binary telluride film, due to the extremely high mobility.
