Thermoelectric Performance of Na-Doped GeSe
Recently, hole-doped GeSe materials have been predicted to exhibit extraordinary thermoelectric performance owing largely to extremely low thermal conductivity. However, experimental research on the thermoelectric properties of GeSe has received less attention. Here, we have synthesized polycrystalline Na-doped GeSe compounds, characterized their crystal structure, and measured their thermoelec...

متن کاملStable respiratory activity requires both P/Q-type and N-type voltage-gated calcium channels.
P/Q-type voltage-gated calcium channels (Ca(v)2.1) play critical presynaptic and postsynaptic roles throughout the nervous system and have been implicated in a variety of neurological disorders. Here we report that mice with a genetic ablation of the Ca(v)2.1 pore-forming α(1A) subunit (α(1A)⁻/⁻) encoded by CACNA1a (Jun et al., 1999) suffer during postnatal development from increasing breathing...
متن کاملn-type thermoelectric material Mg2Sn0.75Ge0.25 for high power generation.
Thermoelectric power generation is one of the most promising techniques to use the huge amount of waste heat and solar energy. Traditionally, high thermoelectric figure-of-merit, ZT, has been the only parameter pursued for high conversion efficiency. Here, we emphasize that a high power factor (PF) is equivalently important for high power generation, in addition to high efficiency. A new n-type...
متن کاملThermal stability and thermoelectric properties of p-type Ba8Ga16Ge30 clathrates
The thermal stability of p-type Ba8Ga16Ge30 clathrates grown from gallium flux has been tested by heat treatment in low pressure Ar atmosphere at 400, 600, and 800 °C. Significant gallium loss was observed for all samples during heat treatment. The treatment at 400 °C does not significantly change the sample properties, and the samples remain p-type and comparable to the untreated, as-prepared,...
