- 1. J. Appl. Phys. 99, 011101 (2006) , “Degradation of hexagonal silicon-carbide-based bipolar devices”, M. Skowronski and S. HaOnly a few years ago, an account of degradation of silicon carbide high-voltage p-i-n diodes was presented at the European Conference on Silicon Carbide and Related Compounds (Kloster Banz, Germany, 2000). This report was followed by the intense effort of multiple groups... (Read more)
- 2. J. Appl. Phys. 98, 053707 (2005) , “An asymmetry of conduction mechanisms and charge trapping in thin high-k HfxTiySizO films”, A. Paskaleva, A. J. Bauer, M. LembergerThe electrical behavior of high-permittivity (high-k) hafnium titanium silicate (HfxTiySizO) layers with different Hf:Ti ratios in the films is investigated. The films were deposited by metal-organic chemical-vapor deposition using a... (Read more)
- 3. Microelectron. Reliability 45, 71 (2005) , “A comprehensive model of PMOS NBTI degradation ”,Negative bias temperature instability has become an important reliability concern for ultra-scaled Silicon IC technology with significant implications for both analog and digital circuit design. In this paper, we construct a comprehensive model for NBTI phenomena within the framework of the standard reaction–diffusion model. We demonstrate how to solve the reaction–diffusion equations in a way that emphasizes the physical aspects of the degradation process and allows easy generalization of the existing work. We also augment this basic reaction–diffusion model by including the temperature and field-dependence of the NBTI phenomena so that reliability projections can be made under arbitrary circuit operating conditions.

- 4. Appl. Phys. Lett. 82, 269 (2003) , “Relationship between interfacial nitrogen concentration and activation energies of fixed-charge trapping and interface state generation under bias-temperature stress condition”,The influence of nitrogen concentration at a nitrided oxide/silicon interface on the activation energies of both near-interface fixed-charge trapping and interface state generation caused by negative bias temperature instability stress has been studied quantitatively. It is observed that the charge... (Read more)
- 5. Phys. Rev. B 43, 6569 (1991) , “Optically detected magnetic resonance of dislocations in silicon”, V. Kveder, P. Omling, H. G. Grimmeiss, Yu. A. OsipyanThe observation of optically detected magnetic resonance (ODMR) signals directly correlated with dislocations in silicon is reported. The ODMR signals are identified as resonances from free electrons, dangling bonds, and quasifree holes bound to a one-dimensional potential in straight dislocations.... (Read more)
- 6. Appl. Phys. Lett. 49, 348-350 (1986) , “Interface traps and Pb centers in oxidized (100) silicon wafers”, G. J. Gerardi, E. H. Poindexter, P. J. Caplan, N. M. JohnsonThe band-gap energy distribution of Pb centers on oxidized (100) Si wafers has been determined and compared with interface electrical trap density Dit. Two different Pb centers are observed on (100) Si: Pb0,... (Read more)
- 7. Appl. Phys. Lett. 46, 787 (1985) , “Absence of oxygen diffusion during hydrogen passivation of shallow-acceptor impurities in single-crystal silicon”, N. M. Johnson and M. D. MoyerIt was recently proposed that hydrogen compensation of shallow-acceptor impurities in single-crystal silicon is due to the diffusion of both monatomic oxygen and hydrogen into silicon which combine at acceptor sites to form neutral acceptor-OH complexes. It is shown here that oxygen does not diffuse... (Read more)
- 8. J. Appl. Phys. 56, 2844-2849 (1984) , “Electronic traps and Pb centers at the Si/SiO2 interface: Band-gap energy distribution”, E. H. Poindexter, G. J. Gerardi, M. -E. Rueckel, P. J. Caplan, N. M. Johnson, D. K. BiegelsenEnergy distribution of Pb centers (·SiSi3) and electronic traps (Dit) at the Si/SiO2 interface in metal-oxide-silicon (MOS) structures was examined by electric-field-controlled electron paramagnetic resonance (EPR)...

- 9. phys. stat. sol. (a) 72, 701-713 (1982) , “On the Energy Spectrum of Dislocations in Silicon”, V. V. Kveder, Yu. A. Osipyan, W. Schrter, G. Zoth.Using deep level transient spectroscopy (DLTS) the defects introduced into silicon by plastic deformation are investigated with respect to their capture and emission characteristics. In agreement with what has been found by electron spin resonance (EPR), kind and density of the detected localized... (Read more)
- 10. Phys. Rev. B 14, 4506 (1976) , “EPR study of neutron-irradiated silicon: A positive charge state of the <100> split di-interstitial”, Young-Hoon Lee, Nikolai N. Gerasimenko, and James W. CorbettThe Si-P6 spectrum shows an intrinsic tetragonal symmetry with the C2 axis along ?100? and distortion forces the principal axes of the g tensor to be displaced in the {100} plane. The g tensor previously identified by Jung and Newell was found to be due to the motionally averaged state... (Read more)
- 11. Phys. Rev. Lett. 36, 1329 (1976) , “EPR Observation of the Isolated Interstitial Carbon Atom in Silicon ”, G. D. Watkins and K. L. BrowerAn EPR spectrum, labeled Si-G12, is identified as arising from an isolated interstitial carbon atom in silicon. A ?100? C-Si interstitialcy model is suggested for the defect in which a silicon and carbon atom pair partially share single substitutional site. Because carbon is isoelectronic with... (Read more)
