The silicon dioxide layers fulfil the chemical stability requirements; however, their surface and interface charges have effect on the silicon surface potential barrier. Positive charge is usually assumed at the oxide-silicon interface, thus depletion or inversion layer develops in the case of p and accumulation in the case of n-type silicon. The surface of silicon dioxide can be charged macroscopically by corona charger or by conductive rubber stamp, microscopically by a tip of some scanning probe microscope (STM or AFM). The oxide surface usually retains the charges for a long time, however in the case of ultra-thin or other leaky oxide continuous charging it is necessary to keep the constant surface potential. The main purpose of this work is to summarize the possibilities of charging up the surface, the effect of the surface and interface charge on the surface properties of the silicon. The rearrangement of the surface charges will also be discussed. (c) 2006 Elsevier B.V.

These methods are sensitive for the work function change and for the PSi-silicon interface potential barrier. The porous silicon (PSi) layer contains huge number of volume traps. Theoretical considerations support the high band bending (near to intrinsic condition or inversion) at the PSi-silicon interface, as high charge carrier concentration at the interface would result in high charge injection into the porous silicon. SPV and vibrating capacitor experiments show that the PSi volume charge and PSi-silicon interface charge tends to shift the interface to depleted state, near to the intrinsic condition (Fermi-level pinning). The interface conditions are summarised in the article and compared with the surface properties of the earlier discussed silicon-dioxide-covered silicon system. Light excitation can affect the charge stored in the PSi, thus the potential barrier at the PSi-silicon interface: the light induced surface voltage transients reveal this charge injection effect.
