摘要：

The numerous studies of electrical transport in undoped hydrogenated microcrystalline silicon (mu c-Si:H) failed so far to establish an agreement of where does the current flow in this heterogeneous system. Here we present a comprehensive local probe investigation that solves this intriguing question and sets up a self consistent picture of the conduction mechanisms and routes in this system. The corresponding significance regarding the emerging field of percolation in semiconductor composites and the related photovoltaic applications are discussed.
