Low-temperature electronic transport behaviour of powder-metallurgical SiGe alloys
Electronic transport properties of mechanically alloyed phosphorous-doped SiGe alloys at low temperatures were examined. We found that in this granular medium hop**-processes show an influence on the electronic...

Non-classical conductivity in a bulk semiconductor up to 35 K
We observed non-classical contributions to the conductivity in three-dimensional samples at temperatures up to 35 K. The experiments were carried out inn-type Hg0.8Cd0.2Te samples having dimensions as large as 8 ...
