Abstract

Nanoassembled Si thin films on conducting glass have been prepared. Films are photoactive and demonstrate "n-type" behavior in contact with electrolyte. Good correlation has been found between band gap obtained from luminescence and photocurrent. Up to such a small particle sizes the Si is still indirect optical material. Si nanoparticles demonstrate significantly reduced electron affinity 2.4 eV with much higher position of the bottom of conducting band compared to bulk Si while position of valence band did not change.
