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 ...

Ohmic contacts to p-type Hg0.3Cd0.7Te by metalorganic chemical vapour deposition of HgTe
Ohmic contacts were obtained to p-type Hg0.3Cd0.7Te crystals by metalorganic chemical vapour deposition (MOCVD) of HgTe as an interface material between the crystals and the contacting metal. Deposition at a redu...

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...

Influence of SiO2 surface passivation on carrier lifetimes in n-type Hg0.7Cd0.3Te
The influence of an SiO2 surface passivation layer on the electronic transport and carrier recombination properties of n-type Hg0.7Cd0.3Te crystals has been investigated. An increase of the excess carrier lifetim...

Mill setting and microstructural evolution during mechanical alloying of Mg2Si
The mechanical alloying behaviour of magnesium and silicon to form the intermetallic compound Mg2Si and the optimum setting of a planetary ball mill for this task, were examined. For the ductile–brittle magnesium...
