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…

Topological Hall effect in single thick SrRuO3 layers induced by defect engineering

Changan Wang, Ching-Hao Chang, Andreas Herklotz +11

The topological Hall effect (THE) has been discovered in ultrathin SrRuO3 (SRO) films, where the interface between the SRO layer and another oxide layer breaks the inversion symmet…
