Silicon in an External E-Field

  1. Hello!

    I was wondering what would happen if you placed a piece of undoped Si in an external electric field (say, between the plates of a capacitor) under illumination. Would it generate current?

    I'm essentially trying to understand if a large enough external electric field could split an electron-hole pair in the same manner as a p-n junction.

    Sorry if it is a dumb question and I really appreciate any responses.

    Thanks!

  3. Sounds like an experiment someone I know wanted to do - put a SiO2-like material in electric field and measure the photoluminescence spectrum... the experiment was never done.

    I would go back to basics and study the effect of electric field on dielectrics to get an idea what to expect... All the best!
