Witryna1 paź 2024 · It has been found that the doped Ga has a distinct role in PbTe and PbSe compounds though they possess the same crystal structure. Therefore, to understand how the thermoelectric performance evolves in the Ga-doped PbTe 1-x Se x solid solution is crucial. Herein, we report that a maximum ZT value of 1.57 at 721 K and a … Witryna11 sie 2008 · The physics of deep defect states associated with group-III (Ga, In, Tl) impurities in PbTe has been of great interest over the last several decades. Three different models have been proposed to understand interesting and unusual properties exhibited by these impurities. These are ``impurity level'' model, ``mixed-valence'' …
WitrynaGa 2 O 3 is attractive for power devices and solar-blind ultraviolet photodetectors due to its ultra-wide bandgap, large breakdown field, and favorable stability. However, it is difficult to prepare the ideal Ga 2 O 3 since there are plenty of defects (e.g., vacancies and interstitial atoms) in the bulk and films which can affect the physical properties of …
