Electronic Transport in Phosphorus-Doped Silicon Nanocrystal Networks
Andre R. Stegner,Rui N. Pereira,K. Klein,Robert Lechner,Roland Dietmueller,Martin S. Brandt,Martin Stutzmann,Hartmut Wiggers +7 more
TL;DR: Investigation of the role of doping and paramagnetic states on the electronic transport of networks assembled from freestanding Si nanocrystals shows that different subsets of P-doped nanocrystal contribute to the different transport processes.

Electronic transport through Si nanocrystal films: Spin-dependent conductivity studies
Rui N. Pereira,Andre R. Stegner,K. Klein,Robert Lechner,Roland Dietmueller,Hartmut Wiggers,Martin S. Brandt,Martin Stutzmann +7 more
TL;DR: In this paper, the authors investigated paramagnetic defects and their influence on the charge transport in thin films composed of Si nanocrystals by means of electrically detected magnetic resonance (EDMR) and conventional electron paramagnetic resonance (EPR).
