Electron paramagnetic resonance (EPR) and photo-EPR studies of aggregate centers with two iron atoms in silicon
We have investigated iron by EPR (electron paramagnetic resonance) and photo-EPR in initially boron doped silicon samples in which the iron concentration exceeded the boron content. A new EPR spectrum, showing...

Nickel in silicon studied by electron paramagnetic resonance
We have investigated nickel in silicon samples with a wide range of initial do** concentrations by EPR, DLTS and photo-EPR techniques. Our results show that the two different Ni-centers which were observed p...

Die „Aktivierungslänge“ bei der thermischen Versetzungsbewegung über Hindernisse auf der Gleitebene
The thermally activated movement of dislocations over a statistical distribution of obstacles in the slip planes is considered. The mean free length of the dislocation between obstacles is calculated as a func...
