Journal ArticleDOI
Recent progress in p-type thermoelectric magnesium silicide based solid solutions
TL;DR: In this article, the effect of doping on thermoelectric properties of magnesium silicide-based solid solutions was investigated and the interplay between the thermodynamic properties and composition, electronic band structure, and doping effect was investigated.
Journal ArticleDOI
A high-temperature stable spectrally-selective solar absorber based on cermet of titanium nitride in SiO2 deposited on lanthanum aluminate
TL;DR: In this article, the authors explored a new absorber with cermet of TiN in SiO2 on LaAlO3 substrate that can be used for long term at 700°C.
