- 1. 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)
- 2. 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)
- 3. Phys. Rev. B 59, 12900 (1999) , “Electron-paramagnetic-resonance measurements on the divacancy defect center R4/W6 in diamond”, D. J. Twitchen, M. E. Newton, J. M. Baker, T. R. Anthony, W. F. BanholzerElectron-paramagnetic-resonance (EPR) studies in radiation damaged diamond enriched to 5% 13C have resulted in the identification of the nearest-neighbor divacancy center. It is the isotopic enrichment, and consequent observation of 13C hyperfine lines, that has permitted the... (Read more)
- 4. 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...

- 5. Phys. Rev. Lett. 73, 3419 (1994) , “Non-Arrhenius Reorientation Kinetics for the B-H Complex in Si: Evidence for Thermally Assisted Tunneling”, Y. Michael Cheng and Michael StavolaThe B-H complex in Si can be aligned by stress and reorients with an activation energy of roughly 0.2 eV. We combine new measurements of the reorientation kinetics of the B-H complex made by the stress-induced dichroism technique with previous internal friction results to show that the reorientation...

- 6. Appl. Phys. Lett. 59, 3165 (1991) , “Hydrogen diffusivities below room temperature in silicon evaluated from the photoinduced dissociation of hydrogen–carbon complexes”, Yoichi Kamiura, Minoru Yoneta, and Fumio HashimotoWe have evaluated hydrogen and deuterium diffusivities in silicon below room temperature (220–270 K) by analyzing the kinetics of photoinduced dissociation of a chemical etching introduced hydrogen (deuterium)–carbon complex. Under sufficiently strong illumination, the annihilation rate... (Read more)
- 7. Phys. Rev. Lett. 61, 2786 (1988) , “Hydrogen Motion in Defect Complexes: Reorientation Kinetics of the B-H Complex in Silicon”, Michael Stavola, K. Bergman, S. J. Pearton, and J. LopataThe motion of hydrogen in the B-H complex in silicon has been studied. An applied stress is used to produce a preferential alignment of the B-H complex at temperatures sufficiently high for the H to move within the complex (above ∼60 K). This alignment of the complexes is detected by comparing the... (Read more)
