Tailoring the degree of disorder in chalcogenide phase-change materials (PCMs) plays an essential role nonvolatile memory devices and neuro-inspired computing. Upon rapid crystallization from amorphous phase, flagship Ge–Sb–Te PCMs form metastable rocksalt-like structures with unconventionally high concentration vacancies, which results disordered crystals exhibiting Anderson-insulating transpo...

The non-parabolicity, temperature dependence of an effective mass and scattering mechanisms in PbTe, PbSe, PbS are considered. The methods of investigation of non-parabolicity based upon measurement of thermoelectric power in strong magnetic fields and Nernst-Ettingshausen coefficient (together with other kinetic coefficients) are discussed. The results given by these methods are shown and disc...

The research on renewable energy is actively looking into electrocatalysts based transition metal chalcogenides because nanostructured support the higher intrinsic activity for both hydrogen evolution reaction (HER) and oxygen (OER). A major technique facilitating conversion of sustainable electrochemical water splitting. aim review to discuss revelations made when trying alter internal externa...
