An important issue due to the recombination activity of extended defects in the silicon lattice are the dislocations We have investigated two different mc-Si materials which were intentionally doped with germanium in concentrations of 0 5 % to 2 % of weight An influence of the germanium on the distribution of oxygen carbon and the
Germanium is mainly a byproduct of zinc ore processing It is a hard grayish-white element it has a metallic luster and the same crystal structure as diamond and it is brittle like glass In addition it is important to note that germanium is a semiconductor with electrical properties between those of a metal and an insulator The development of the germanium transistor opened the door to
The radiation hardness of Czochralski grown n-type silicon samples doped with germanium (NGe = 21020 cm−3) and without it was investigated after irradiation by fast neutrons The dependence of the effective carrier concentration on fluence was described in the framework of Gossick's corrected model It was found that doping the germanium impurity resulted in increase of n-Si radiation
