The experiment of thermally stimulated charge release has been used in the m.o.s. capacitor to study electron and hole states in the metal-oxide-silicon system. Broadly similar results have been obtained for ‘wet’ and ‘dry’ oxides on ‘mechanically’ and ‘chemically’ polished silicon surfaces. A representative spectrum is presented showing electron and hole interface states spread over most of the energy band gap.
