TLDR
In this paper, a new interpretation of the conductivity of thin amorphous Ge and Si is presented based on a transition from percolation conduction to Miller and Abrahams's conduction at small film thickness.Abstract:
We present a new interpretation of the anisotropy of the conductivity in thin films of amorphous Ge and Si. The interpretation is based on a transition from percolation conduction to Miller and Abrahams's conduction at small film thickness. A simple theory, together with experimental data, is presented. The comparison between them is found to be good.read more

Electrical conduction in chalcogenide glasses of phase change memory
TL;DR: In this article, the authors consolidate and expand the current state of knowledge related to dc conduction in chalcogenides and present twelve relevant transport mechanisms with conductivities that depend exponentially on the electric field, including Poole-Frenkel ionization, Schottky emission, hopping conduction, field-induced delocalization of tail states, space-charge-limited current, field emission, percolation band conduction and transport through crystalline inclusions.

Effects of nonuniformity in thin-film photovoltaics
TL;DR: In this article, the physical origin and effects of micrononuniformities on thin-film photovoltaics were discussed and the effect of microdiodes of low open circuit voltages were shown to affect macroscopically large regions.
