Electron-paramagnetic-resonance study of heat-treatment centers in n-type silicon

Abstract
Donor formation in heat-treated phosphorus-doped Czochralski-grown silicon has been studied by electron paramagnetic resonance and resistivity measurements. Both ‘‘thermal-donor-’’ and ‘‘new-donor’’-formation temperature regions (470 and 650 °C, respectively) have been investigated. The results allow one to identify the spectra in both regions as arising from the Si-NL10 defect.
