Abstract
A method for producing a porous nanocrystalline semiconductor layer (100) is provided, including: a) providing a substrate (10) having a substrate surface; b) coating a semiconductor layer (12) on the substrate surface; c) coating a metal containing layer (14) on the semiconductor layer; d) heat treating the semiconductor layer and the metal containing layer at a temperature and for a time period such that the semiconductor and the metal partially interdiffuse and the semiconductor is at least partially crystallized; and e) least partially removing the metal. Further, a porous nanocrystalline semiconductor layer, a use thereof, an anode, and a secondary lithium-ion battery are provided.
