# Electron hole pair

phrygian
When an electron in a semiconductor is excited to a higher state, an electron hole pair is created. How does this not violate charge conservation, a charge of +e turns into a net charge of 0?

Thanks for the help

....a charge of +e turns into a net charge of 0?

It is not clear as to what you mean by this. Where is +e charge which is converted to 0 charge?
