Thermoelectrics, enabling the direct energy conversion between electricity and heat, provide
alternatives for conventional power generation and refrigeration with considerable …

This review provides a summary of the rich physics expressed within SrTiO 3-based
heterostructures and nanostructures. The intended audience is researchers who are …

It is highly desirable to discover photovoltaic mechanisms that enable enhanced efficiency of
solar cells. Here we report that the bulk photovoltaic effect, which is free from the …

Electronic and optical properties of materials are affected by atomic motion through the
electron–phonon interaction: not only band gaps change with temperature, but even at …

We report a systematic investigation of orthorhombic perovskite-type R CrO 3 powder
samples by Raman scattering for nine different rare earth R 3+ cations (R= Y, La, Pr, Sm, Gd …

Phase transitions in ABX 3 perovskites are often accompanied by rigid rotations of the
corner-connected BX 6 octahedral network. Although the mechanisms for the preferred …

Despite the rapid development and enormous success of organic–inorganic hybrid halide
perovskites (AB′ X 3), such as CH3NH3PbI3 as absorbers for perovskite-based solar cells …

Numerous of the greatest inventions in modern society, such as solar cells, display panels,
and transistors, rely on a simple concept: An external stimulus is applied to a material and …

Seismology records the presence of various heterogeneities throughout the lower mantle,,
but the origins of these signals—whether thermal or chemical—remain uncertain, and …

In the present work structural and optoelectronic properties of alkali niobates ANbO 3 (A=
Na, K and Rb) are investigated in different crystal structures eg cubic, tetragonal …
