Studies of the Si-SiO2 interface by MeV ion channeling

Abstract
By performing backscattering‐channeling measurements in two different geometries on thin Si crystals thermally oxidized at 800 °C, we have obtained upper and lower limits of the number of reconstructed Si layers at the Si‐SiO2 interface. The results indicate an abrupt Si‐SiO2 interface with one to two monolayers of Si reconstruction.
