- 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...

- 2. J. Appl. Phys. 100, 033525 (2006) , “Determination of interstitial oxygen concentration in germanium by infrared absorption”, V. V. Litvinov, B. G. Svensson, L. I. Murin, J. L. Lindström, V. P. Markevich, and A. R. PeakerThe intensities of infrared absorption due to the asymmetric stretching vibrations of interstitial oxygen atoms in Ge crystals enriched with 16O and 18O isotopes have been compared with oxygen concentrations determined by means of secondary ion mass spectrometry. For Ge samples... (Read more)
- 3. Phys. Rev. B 74, 165203 (2006) , “Isotopic-mass dependence of the A, B, and C excitonic band gaps in ZnO at low temperatures”, S. Tsoi, X. Lu, A. K. Ramdas, H. Alawadhi, M. Grimsditch, M. Cardona, and R. LauckLow temperature wavelength-modulated reflectivity measurements of isotopically engineered ZnO samples have yielded the dependence of their A, B, and C excitonic band gaps on the isotopic masses of Zn and O. The observed dependence is analyzed in terms of the band gap renormalization by zero-point... (Read more)
- 4. Phys. Rev. B 73, 235209 (2006) , “Temperature dependence of the vibrational spectrum of a Li-OH complex in ZnO: Infrared absorption experiments and theory”, Kevin R. Martin, Philip Blaney, Gang Shi, Michael Stavola, and W. Beall FowlerConsiderable interest has developed in the potential use of IIVI oxides as electronic and optical materials. In several cases, alkali atoms have been suggested as dopants. We report on the theoretical and experimental investigation of infrared and vibrational properties of a Li-OH complex in... (Read more)
- 5. Appl. Phys. Lett. 87, 172108 (2005) , “Production of native donors in ZnO by annealing at high temperature in Zn vapor”, L. E. Halliburton, N. C. Giles, N. Y. Garces, Ming Luo, Chunchuan Xu, Lihai Bai, L. A. BoatnerZinc oxide crystals grown by the seeded chemical vapor transport method have been annealed in zinc vapor at 1100 °C for 30 min. These thermochemical reduction treatments produce a deep red coloration in the crystals and increase their n-type electrical conductivity. Electron paramagnetic... (Read more)
- 6. Appl. Surf. Sci. 180, 308-314 (2001) , “The surface properties and photocatalytic activities of ZnO ultrafine particles”, Liqiang Jing, Zili Xu, Xiaojun Sun, Jing Shang and Weimin CaiWe prepared ZnO ultrafine particles (UFPs) by thermal decomposition of the precursor zinc carbonate hydroxide. The surface properties of the as-prepared particles were studied using TEM, XRD, BET, SPS, EPR, IR, and XPS. The surface contains active species such as oxygen deficiencies and hydroxyl...

- 7. Phys. Rev. Lett. 87, 235501 (2001) , “Thermal Double Donors and Quantum Dots”, J. Coutinho, R. Jones, L. I. Murin, V. P. Markevich, J. L. Lindström, S. Öberg, P. R. Briddon.Combined local mode spectroscopy and ab initio modeling are used to demonstrate for the first time that oxygen atoms in thermal double donors (TDD) in Si are in close proximity. The observed vibrational modes in 16O, 18O, and mixed isotopic samples are consistent with a model... (Read more)
- 8. Mater. Sci. Eng. B 58, 171-178 (1999) , “Self-Interstitial Related Reactions in Silicon Irradiated by Light Ions”, B. N. Mukashev, Kh. A. Abdullin, Yu. V. Gorelkinskii and S. Zh. TokmoldinRecent deep level transient spectroscopy (DLTS), electron paramagnetic resonance (EPR) and infrared (IR) spectroscopy data on interactions of self-interstitial with carbon, aluminium, oxygen and hydrogen in silicon irradiated by light ions are reviewed. Self-interstitial behaviour in silicon was... (Read more)
- 9. Jpn. J. Appl. Phys. 34, 5483-5488 (1995) , “Effects of Grown-in Hydrogen on Lifetime of Czochralski Silicon Crystals ”, Akito HaraI studied the effects of grown-in hydrogen on the lifetime of Czochralski-grown silicon crystals. It was found that grown-in hydrogen degraded the electrical properties of Czochralski-grown silicon crystals by enhancing the formation of recombination centers, which had a high thermal stability...

Hosono, H. Kawazoe, K. Oyoshi, S. TanakaElectron paramagnetic resonance spectra were measured on SiO2 glasses implanted with Si ions to a fluence of 6 × 1016 cm−2 at an acceleration voltage of 160 kV. Three sets of doublets with different separation were observed in Si29-implanted substrates and were ascribed to primary... (Read more)

McDonaldInfrared and electron-spin-resonance measurements on the recovery of silicon irradiated with 1.5-MeV electrons are presented. In the infrared measurements the disappearance of the previously reported 829-cm-1 (12?) oxygen vibration band is followed, and the appearance and subsequent... (Read more)
