- 1. Appl. Phys. Lett. 88, 242110 (2006) , “Electrical characterization of defects introduced during electron beam deposition of Pd Schottky contacts on n-type Ge”, F. D. Auret, W. E. Meyer, S. Coelho, and M. HayesWe have investigated by deep level transient spectroscopy the hole and electron trap defects introduced in n-type Ge during electron beam deposition (EBD) of Pd Schottky contacts. We have also compared the properties of these defects with those introduced in the same material during... (Read more)
- 2. J. Appl. Phys. 100, 023709 (2006) , “Effect of threading dislocation density on Ni/n-GaN Schottky diode I-V characteristics”, A. R. Arehart, B. Moran, J. S. Speck, U. K. Mishra, S. P. DenBaars, and S. A. RingelThe impact of threading dislocation density on Ni/n-GaN Schottky barrier diode characteristics is investigated using forward biased current-voltage-temperature (I-V-T) and internal photoemission (IPE) measurements. Nominally, identical metal-organic chemical vapor... (Read more)
- 3. J. Appl. Phys. 99, 013515 (2006) , “Defects and electrical behavior in 1 MeV Si+-ion-irradiated 4H–SiC Schottky diodes”, F. Roccaforte, S. Libertino, V. Raineri, A. Ruggiero, V. Massimino, and L. CalcagnoIn this paper, the formation and evolution of defects induced by ion irradiation with 1 MeV Si+ ions in Ni2Si/4HSiC Schottky diodes were studied and correlated with the electrical properties of the contacts. The current-voltage characteristics of the contacts... (Read more)
- 4. 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)
- 5. Phys. Rev. B 74, 235317 (2006) , “Impurity conduction in phosphorus-doped buried-channel silicon-on-insulator field-effect transistors at temperatures between 10 and 295 K”, Yukinori Ono, Jean-Francois Morizur, Katsuhiko Nishiguchi, Kei Takashina, Hiroshi Yamaguchi, Kazuma Hiratsuka, Seiji Horiguchi, Hiroshi Inokawa, and Yasuo TakahashiWe investigate transport in phosphorus-doped buried-channel metal-oxide-semiconductor field-effect transistors at temperatures between 10 and 295 K. We focus on transistors with phosphorus donor concentrations higher than those previously studied, where we expect conduction to rely on donor... (Read more)
- 6. J. Appl. Phys. 94, 7105-7111 (2003) , “Electrically detected magnetic resonance of ion-implantation damage centers in silicon large-scale integrated circuits”, T. Umeda, Y. Mochizuki, K. Okonogi, K. HamadaWe used electrically detected magnetic resonance to study the microscopic structure of ion-implantation-induced point defects that remained in large-scale Si integrated circuits (Si LSIs). Two types of defects were detected in the source/drain (n+-type) region of... (Read more)
- 7. Appl. Phys. Lett. 80, 1261-1263 (2002) , “Hole trapping in ultrathin Al2O3 and ZrO2 insulators on silicon”, V. V. Afanas'ev and A. 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)
- 8. Jpn. J. Appl. Phys. 37, 1939-1944 (1999) , “Role of the EL2 Center on the Formation of Metastable Hydrogen-related Defects (M3/M4) in n-GaAs”, T. Shinagawa, T. OkumuraHydrogen-related metastable defects (M3/M4) in n-GaAs were studied in relation to the EL2 center. We found that the M3/M4 defects were observed only in the crystals containing the EL2 center in the as-grown state after exposure to a hydrogen plasma. The EL3 level, which was tentatively assigned as... (Read more)
- 9. Appl. Phys. Lett. 56, 949 (1991) , “Evidence for the existence of a negatively charged hydrogen species in plasma-treated n-type Si”, A. J. Tavendale, S. J. Pearton, A. A. WilliamsWe demonstrate the drift of a donor-passivating hydrogen species under the action of the electric field in the depletion region of a reverse-biased Au/n-Si Schottky diode hydrogenated by exposure to a low-frequency discharge. The redistribution is explained by the unidirectional drift of a... (Read more)

- 11. Phys. Rev. B 41, 12354-12357 (1990) , “Negative-charge state of hydrogen in silicon”, J. Zhu, N. M. Johnson, and C. HerringIt is demonstrated that hydrogen can migrate in silicon as a negatively charged species (H-). The evidence is the combined observation of a strong electric-field dependence in the rate of removal of PH complexes during bias-temperature stress of hydrogenated Schottky-barrier diodes and...

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)...

CaplanOn unannealed, thermally oxidized silicon, electron spin resonance reveals an oriented interface defect which is termed the Pb center and identified as the trivalent silicon defect. Deep level transient spectroscopy (DLTS) reveals two broad characteristic peaks in the... (Read more)
