- 1. Appl. Phys. Lett. 89, 092120 (2006) , “Defect generation at SiO2/Si interfaces by low pressure chemical vapor deposition of silicon nitride”, Hao Jin, K. J. Weber, and P. J. 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)
- 2. Phys. Rev. Lett. 92, 105505 (2004) , “In situ ESR Observation of Interface Dangling Bond Formation Processes During Ultrathin SiO2 Growth on Si(111)”, W. Futako, N. Mizuochi, and S. YamasakiWe report the formation processes of interface dangling bonds (Pb centers) during initial oxidation of a clean Si(111) surface using an ultrahigh-vacuum electron-spin-resonance technique. At the oxidation of one or two Si layer(s), the Pb center... (Read more)
- 3. Appl. Phys. Lett. 81, 1128-1130 (2002) , “Electron spin resonance study of interface defects in atomic layer deposited hafnium oxide on Si”, A. Y. Kang, P. M. Lenahan, J. F. Conley Jr., R. 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)
- 4. Phys. Rev. Lett. 87, 165506 (2001) , “Defect Generation by Hydrogen at the Si-SiO2 Interfaces”, S. N. Rashkeev, D. M. Fleetwood, R. D. Schrimpf, and S. T. PantelidesHydrogen is known to passivate Si dangling bonds at the Si-SiO 2 interface, but the subsequent arrival of H + at the interface causes depassivation of Si-H bonds. Here we report first-principles density functional calculations, showing that, contrary to conventional... (Read more)
- 5. Phys. Rev. Lett. 85, 2773-2776 (2000) , “Dangling Bond Defects at Si-SiO2 Interfaces: Atomic Structure of the Pb1 Center”, A. Stirling, A. Pasquarello, J.-C. Charlier, R. CarUsing a first-principles approach, we characterize dangling bond defects at Si-SiO2 interfaces by calculating hyperfine parameters for several relaxed structures. Interface models, in which defect Si atoms remain close to crystalline sites of the substrate upon relaxation, successfully... (Read more)
- 6. J. Vac. Sci. Technol. B 16, 2134-2153 (1998) , “What can electron paramagnetic resonance tell us about the Si/SiO2 system?”, P. M. Lenahan, J. F. Conley, Jr.Electron paramagnetic resonance (EPR) measurements of Si/SiO2 systems began over 30 years ago. Most EPR studies of Si/SiO2 systems have dealt with two families of defects: Pb centers and E centers. Several variants from each group have...

- 7. Phys. Rev. Lett. 72, 2745-2748 (1994) , “Atomic Hydrogen Reactions with Pb Centers at the (100) Si/SiO2 Interface”, J. H. Stathis, E. CartierWe have investigated the reaction of atomic hydrogen with defects at the (100) Si/SiO2 interface. Similar to previous results on the (111) interface, we find that the two paramagnetic defects at the (100) interface, Pb0 and Pb1, are either passivated or produced by... (Read more)

StesmansElectron-spin-resonance (ESR) studies of intrinsic Pb defects at the (111)Si/SiO2 interface have been carried out as a function of oxidation temperature Tox for the range 22<ToxTox and high-Tox...
