Popis: Various approaches are described to synthesize Mn-doped Ge NWs using UHV-CVD growth via the VLS mechanism. We explored in-situ doping using an organo-metallic precursor (TCMn) and tested different catalyst seeds such as Au, Au-Mn or Ge-Mn. All in-situ attempts failed to incorporate Mn atoms into the NW. Moreover we observed that the use of TCMn and/or Au-Mn catalysts have a crippling effect on the growth kinetics. Finally, ex-situ doping with ion implantation is right now considered as a doping alternative. We report on preliminary results aiming at testing the radiation resistance of Ge NWs embedded in a removable silica matrix. (© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
