Dissolution of donor-vacancy clusters in heavily doped n-type germanium
Slawomir Prucnal, Maciej O. Liedke, Xiaoshuang Wang +17
The n-type doping of Ge is a self-limiting process due to the formation of vacancy-donor complexes (DnV with n <= 4) that deactivate the donors. This work unambiguously demonstrate…

Probing ion transport at the nanoscale: Time-domain electrostatic force spectroscopy on glassy electrolytes
A. Schirmeisen, A. Taskiran, H. Fuchs +4
We have carried out time--domain electrostatic force spectroscopy on two different ion conducting glasses using an atomic force microscope. We compare the electrostatic force spect…

Curie temperature and carrier concentration gradients in MBE grown GaMnAs layers
A. Koeder, S. Frank, W. Schoch +10
We report on detailed investigations of the electronic and magnetic properties of ferromagnetic GaMnAs layers, which have been fabricated by low-temperature molecular-beam epitaxy.…
