thermal conductivity of germanium

Technical data for the element Germanium in the …

Lead Tellurides alloyed with Germanium and Silicium - Thermal Conductivity. In the lead telluride materials PbTe-Ge and PbTe-Ge1-xSix the thermal conductivity is easily tuned by alloying Ge with Si and reducing the Ge content [2] . The below shown results are obtained in the temperature range between 25°C and 320°C.

Optical Materials: Germanium (Ge)<

 · Silicene possesses excellent electronic properties and low thermal conductivity and hence is a potential material for thermoelectric applications. The key to improve the thermoelectric efficiency of silicene relies on opening a bandgap to enhance the thermopower and suppressing the lattice thermal conductivity. Based on first-principle calculations, we propose germanium doping as an effective ...

2009-12-4 · We have measured the thermal conductivity of seven germanium crystals with different isotopic composi-tions in the temperature range between 2 K and 300 K. These samples, including one made of highly enriched 70Ge~99.99%!, show intrinsic behavior at room temperature with the exception of a p-type sample with uNd-Nau>231016 cm23.

The thermal conductivity of single crystals o f pure n-type germanium and of p-type germanium containing from 10 14 to 10 19 group III impurity atoms per cm 3 has been measured from 2 to 90° K . In some cases the readings have been extended up to room temperature. Whereas the low- temperature conductivity of the pure specimens is that which one would expect from a dielectric crystal, the ...
