Xe interacting with porous silicon [PDF]
Physical Chemistry Chemical Physics, 2010 Thin films of porous silicon (PS), structurally characterized by HR-SEM, were studied using xenon Temperature Programmed Desorption (TPD) as a probe of its inner pores. Geometric hindrance of the depth desorbing population and multiple wall collisions result in a unique double-peak structure of the TPD curve.

Porous silicon solar cells [PDF]
2015 IEEE 15th International Conference on Nanotechnology (IEEE-NANO), 2015 We developed a new architecture of crystalline solar cell, based on an ultrathin silicon membrane, taking advantage of the technology of porous silicon. The architecture consists of a macro-porous membrane, offering deeply textured surface, capable to efficiently capture the impinging light, absorbed it in the porous structure, and delivering the photo-
