- 1. J. Appl. Phys. 104, 014106 (2008) , “Analysis of electrically biased paramagnetic defect centers in HfO2 and HfxSi1−xO2 / (100)Si interfaces”, P. T. Chen, B. B. Triplett, J. J. Chambers, L. Colombo, P. C. McIntyre, and Y. NishiThis study reports on the first experimental observations of electrically biased paramagnetic defects at 800 °C N2 annealed HfxSi1−xO2 (x=0.4, and 0.6)/(100)Si and HfO2/(100)Si interfaces in metal oxide silicon...

- 2. Appl. Phys. Lett. 89, 152910 (2006) , “Characterization of atomic-layer-deposited Al2O3/GaAs interface improved by NH3 plasma pretreatment”, Hong-Liang Lu, Liang Sun, Shi-Jin Ding, Min Xu, David Wei Zhang, and Li-Kang WangAl2O3 thin films were deposited by atomic layer deposition on HF-cleaned and NH3 plasma-treated GaAs surfaces, respectively. The precursors used for Al2O3 films are trimethylaluminum and water. Effects of NH3 plasma pretreatment on... (Read more)
- 3. Appl. Phys. Lett. 89, 142909 (2006) , “Fluorine passivation in poly-Si/TaN/HfO2 through ion implantation”, M. H. Zhang, F. Zhu, T. Lee, H. S. Kim, I. J. Ok, G. Thareja, L. Yu, and Jack C. LeeFluorine (F) passivation in poly-Si/TaN/HfO2/p-Si gate stacks through gate ion implantation has been studied. It has been found that when the TaN thickness was less than 15 nm, the mobility and subthreshold swing improved significantly in HfO2 n-channel... (Read more)
- 4. J. Appl. Phys. 100, 094108 (2006) , “The effect of interfacial layer properties on the performance of Hf-based gate stack devices”, G. Bersuker, C. S. Park, J. Barnett, P. S. Lysaght, P. D. Kirsch, C. D. Young, R. Choi, B. H. Lee, B. Foran, K. van Benthem, S. J. Pennycook, P. M. Lenahan, and J. T. RyanThe influence of Hf-based dielectrics on the underlying SiO2 interfacial layer (IL) in high-k gate stacks is investigated. An increase in the IL dielectric constant, which correlates to an increase of the positive fixed charge density in the IL, is found to depend on the starting,... (Read more)
- 5. J. Appl. Phys. 100, 024103 (2006) , “Scanning transmission electron microscopy investigations of interfacial layers in HfO2 gate stacks”, Melody P. Agustin, Gennadi Bersuker, Brendan Foran, Lynn A. Boatner, and Susanne StemmerElectron energy-loss spectroscopy combined with high-angle annular dark-field (HAADF) imaging in scanning transmission electron microscopy was used to investigate the chemistry of interfacial layers in HfO2 gate stacks capped with polycrystalline Si gate electrodes. To interpret the... (Read more)
- 6. J. Appl. Phys. 99, 103507 (2006) , “Nonconservative Ostwald ripening of a dislocation loop layer under inert nitrogen-rich SiO2/Si interfaces”, D. Skarlatos, P. Tsouroutas, V. Em. Vamvakas, and C. TsamisIn this work we perform a systematic study of the dissolution of a dislocation loop layer under the influence of inert SiO2/Si and nitrogen-rich SiO2/Si interfaces. The composition of the dislocation loop layer was just after its formation 10%20% Frank dislocation loops... (Read more)
- 7. Phys. Rev. B 67, 195338 (2003) , “Layer-resolved kinetics of Si oxidation investigated using the reflectance difference oscillation method”, T. Yasuda, N. Kumagai, M. Nishizawa, S. Yamasaki, H. Oheda, and K. YamabeDry oxidation kinetics of the Si(001) surface has been investigated using reflectance difference oscillation to resolve atomic-scale phenomena. The activation energy for oxidation has been found to increase as the oxide-Si interface moves in the depth direction, reaching the value for bulk... (Read more)

Yamada-Kaneta.We have previously concluded that the oxygen-precipitate-associated defects that we identified by the deep levels at Ev + 0.30 eV and Ec0.25 eV were the Pb centers generated in the interface between the oxygen...

HeadleyIn this paper a computational model is developed which allows one to calculate the contribution to the Zeeman linewidth arising from magnetic dipole-dipole interactions between unpaired electrons in the dilute limit, which in our specific application correspond to dangling bonds (Pb...
