Thermoelectric devices that are flexible and optically transparent hold unique promise for future electronics. However, development of invisible thermoelectric elements is hindered by the lack of p-type transparent thermoelectric materials. Here we present the superior room-temperature thermoelectric performance of p-type transparent copper iodide (CuI) thin films. Large Seebeck coefficients an...
The ability of some materials with a perfectly ordered crystal structure to mimic the heat conduction of amorphous solids is a remarkable physical property that finds applications in numerous areas of materials science, for example, in the search for more efficient thermoelectric materials that enable to directly convert heat into electricity. Here, we unveil the mechanism in which glass-like t...
The interactions between electrons and lattice vibrations are fundamental to materials behaviour. In the case of group IV-VI, V and related materials, these interactions are strong, and the materials exist near electronic and structural phase transitions. The prototypical example is PbTe whose incipient ferroelectric behaviour has been recently associated with large phonon anharmonicity and the...
The thermoelectric properties of nano-scaled In2O3:Sn films deposited by spray pyrolysis are considered in the present report. It is shown that multicomponent In2O3:Sn-based films are promising material for the application in thermoelectric devices. It is established that the increase in the efficiency of thermoelectric conversion at CSn~5% occurred due to nano-scaled structure of the films stu...
The optoelectronic properties of gallium nitride (GaN) have been well studied for decades, with results being translated to applications in solid state lighting and lasers, thermoelectricity, solar cells, power electronics, etc. However, the mechanical and tribological properties of GaN have been studied and understood far less than its optoelectronic properties. Our research aims to explore th...
As an excellent representative of a new generation semiconductor materials, perovskite materials are sweeping the whole photoelectric field like storm (such as photovoltaic, electroluminescence, detection and imaging, memristor, thermoelectricity, other fields). In show unique application potential imaging. This paper overviews recent advances units (PDUs) based on for First, key characteristic...
