- 1. Phys. Rev. B 75, 085423 (2007) , “Room-temperature atmospheric oxidation of Si nanocrystals after HF etching”, X. D. Pi, L. Mangolini, S. A. Campbell, and U. KortshagenThe effect of HF etching of the silicon oxide shell covering the surface of Si nanocrystals (NCs) on the subsequent room-temperature atmospheric oxidation of Si-NCs has been investigated by means of photoluminescence measurements, Fourier transform infrared spectroscopy, and electron paramagnetic...

J. von Bardeleben, Yue Ke, R. P. Devaty, W. J. ChoykeThe effect of forming gas and vacuum annealing on the concentration of carbon dangling bond (PbC) centers at 3C- and 4H-SiC/SiO2 interfaces has been studied by electron paramagnetic resonance (EPR) spectroscopy. Our results show efficient passivation at 400 °C and... (Read more)
- 3. Microelectron. Reliability 45, 57 (2005) , “Characterization of interface defects related to negative-bias temperature instability SiON/Si<100> systems ”,Interface defects related to negative-bias temperature instability (NBTI) in an ultrathin plasma-nitrided SiON/ Si<100> system were characterized by using conductance–frequency measurements, electron-spin resonance measure- ments, and synchrotron radiation X-ray photoelectron spectroscopy. It was confirmed that NBTI is reduced by using D2-annealing instead of the usual H2-annealing. Interfacial Si dangling bonds (Pb1 and Pb0 centers) were detected in a sample subjected to negative-bias temperature stress (NBTS). Although we suggest that NBTS also generates non-Pb defects, it does not seem to generate nitrogen dangling bonds. These results show that NBTI of the plasma-nitrided SiON/Si system is predominantly due to Pb depassivation. Plasma nitridation was also found to increase the Pb1/Pb0 density ratio, modify the Pb1 defect structure, and increase the latent interface trap density by generating Si suboxides at the interface. These changes are likely to be the causes of NBTI in ultrathin plasma-nitrided SiON/Si systems. (Read more)

Stesmans.An electron-spin-resonance study has been carried out, both isothermally and isochronically, of the recovery under vacuum annealing from the hydrogen passivated state (symbolized as HPb) of paramagnetic Pb centers (Si3?Si?) at the (111)Si/SiO2...

Stesmans.The thermal interaction kinetics of interfacial Si dangling bond Pb defects (Si3≡Si·) in (1 1 1)Si/SiO2, including passivation in molecular hydrogen (pictured as PbH formation) and dissociation in vacuum, is readdressed. An initial simple thermal model had concluded simple exponential... (Read more)

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...

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)
