- 1. Appl. Phys. Lett. 89, 112121 (2006) , “Nature and stability of the (100)Si/LaAlO3 interface probed by paramagnetic defects”, A. Stesmans, K. Clémer, V. V. Afanas'ev, L. F. Edge, and D. G. SchlomElectron spin resonance analysis of (100)Si/LaAlO3 structures reveals the absence of a Si/SiO2-type interface in terms of archetypal Si-dangling bond-type Si/SiO2 interface defects (Pb0,Pb1). With no... (Read more)

SmithLow pressure chemical vapor deposition of Si3N4 on oxidized Si (111) surfaces causes a change in the properties of the dominant interface defect, the Pb center, observed by electron paramagnetic resonance. The change in the signature of the... (Read more)

Conley Jr.We observed two paramagnetic defects in thin films of HfO2 on silicon with electron spin resonance. Both appear after photoinjecting electrons into the dielectric. Strong spectroscopic evidence links one spectrum to an O2-" align="middle"> defect. A second spectrum is... (Read more)

SolankiWe report electron spin resonance (ESR) observation of interface defects at the HfO2/(111)Si boundary for HfO2 films deposited via atomic layer chemical vapor deposition using Hf(NO3)4 as a precursor. We observe several signals, dominated by one due to a... (Read more)

Afanas'evThe structural degradation of thermal SiO2 on (100)Si under isochronal vacuum annealing in the range Tan = 950 °C1250 °C was monitored by electron spin resonance (ESR) in terms of point defect creation, including...

StesmansOptical injection of electron-hole pairs in 35 nm thick layers of SiO2, Al2O3, ZrO2 and their stacks on (100)Si is found to result in positive oxide charging, suggesting trapping of holes. In thin layers of the high-permittivity metal oxides... (Read more)
- 7. Mater. Sci. Eng. B 73, 60-63 (2000) , “EPR study of He-implanted Si”, B. Pivac, B. Rakvin, R. Tonini, F. Corni and G. OttavianiElectron paramagnetic resonance has been used to study the influence of thermal treatments on defect evolution in helium-implanted Czochralski single-crystal silicon. It is shown that the thermal treatment induces helium migration and capturing by vacancy clusters that transform into pressurized... (Read more)

TanakaElectronic structures of the light-induced electron spin resonance (LESR) centers in undoped a-Si:H have been investigated by means of pulsed ESR techniques. Overlapping LESR signals of g?=?2.004 and 2.01 have been experimentally deconvoluted by using the difference in spin-lattice relaxation time...
