Jf. Conley et al., ELECTRON-SPIN-RESONANCE EVIDENCE FOR THE STRUCTURE OF A SWITCHING OXIDE TRAP - LONG-TERM STRUCTURAL-CHANGE AT SILICON DANGLING BOND SITES IN SIO2, Applied physics letters, 67(15), 1995, pp. 2179-2181
We provide direct and unambiguous experimental spectroscopic evidence
for the structure of a switching oxide trap in thermally grown SiO2 ga
te oxides on Si. Switching oxide traps can ''switch'' charge state in
response to changes in the voltage applied to the gate of a metal-oxid
e-semiconductor field-effect transistor. Electron spin resonance measu
rements reveal that some E'(gamma) centers (a hole trapped at an oxyge
n vacancy) can behave as switching oxide traps. (C) 1995 American Inst
