Porous and Nanoporous Semiconductors and Emerging Applications

[摘要] Pores in single-crystalline semiconductors can be produced in a wide range of geometries and morphologies, includingthe “nanometer” regime. Porous semiconductors may have properties completely different from the bulk, and metamaterials with, for example, optical properties not encountered in natural materials are emerging. Possible applications of porous semiconductors include various novel sensors, but also more “exotic” uses as, for example, high explosives or electrodes for micro-fuel cells. The paper briefly reviews pore formation (including more applied aspects of large area etching), properties of porous semiconductors, and emerging applications.
