- 1. J. Appl. Phys. 99, 093108 (2006) , “Extremely high quantum efficiency of donor-acceptor-pair emission in N-and-B-doped 6H-SiC”, S. Kamiyama, T. Maeda, Y. Nakamura, M. Iwaya, H. Amano, I. Akasaki, H. Kinoshita, T. Furusho, M. Yoshimoto, T. Kimoto, J. Suda, A. Henry, I. G. Ivanov, J. P. Bergman, B. Monemar, T. Onuma, and S. F. ChichibuHigh-efficiency visible light emission in N-and-B-doped 6H-SiC epilayers was observed in photoluminescence measurements at room temperature. The orange-yellow light emission due to the recombination of donor-acceptor pairs (DAPs) has a broad spectrum with a peak wavelength of 576 nm and a... (Read more)

- 3. Physica B 340-342, 15-24 (2003) , “Defects in SiC”, E. Janzén, I. G. Ivanov, N. T. Son, B. Magnusson, Z. Zolnai, A. Henry, J. P. Bergman, L. Storasta, F. CarlssonRecent results from studies of shallow donors, pseudodonors, and deep level defects in SiC are presented. The selection rules for transitions between the electronic levels of shallow donors in 4H–SiC in the dipole approximation are derived and the ionization energy for the N donor at... (Read more)
- 4. J. Appl. Phys. 91, 8919-8941 (2002) , “Transient Enhanced Diffusion of Boron in Si”, S. C. Jain, W. Schoenmaker, R. Lindsay, P. A. Stolk, S. Decoutere, M. Willander, H. E. Maes.On annealing a boron implanted Si sample at ~800 °C, boron in the tail of the implanted profile diffuses very fast, faster than the normal thermal diffusion by a factor 100 or more. After annealing for a sufficiently long time, the enhanced diffusion saturates. The enhanced diffusion is... (Read more)
- 5. Physica B 308-310, 691 (2001) , “Contactless studies of semi-insulating 4H–SiC”, W. E. Carlos, W. J. Moore, G. C. B Braga, J. A. Freitas, Jr. , E. R. Glaser and B. V. ShanabrookSemi-insulating (SI) silicon carbide is important for applications in high-power, high-frequency electronics, such as SiC MESFETs and GaN FETs. In this work, we discuss the use of low-temperature electron paramagnetic resonance (EPR), room- and low-temperature FTIR and photoluminescence as potential... (Read more)
- 6. phys. stat. sol. (a) 162, 95-151 (1997) , “EPR and ENDOR Investigations of Shallow Impurities in SiC Polytypes”, S. Greulich-WeberInvestigations of nitrogen donors in 6H-, 4H- and 3C-SiC using conventional electron paramagnetic resonance (EPR), electron nuclear double resonance (ENDOR) and optical detection of EPR and ENDOR as well as optical absorption and emission spectroscopy are reviewed and critically discussed. An... (Read more)
- 7. Phys. Rev. B 7, 4547 (1973) , “Raman Scattering and Photoluminescence in Boron-Doped and Arsenic-Doped Silicon”, J. M. Cherlow, R. L. Aggarwal, and B. LaxThe deformation potentials and g values of the ground state of the boron acceptor in silicon have been determined from a study of the stress and Zeeman splitting of the electronic Raman scattering in this material. The stress splitting of the Raman line results from a twofold splitting of the... (Read more)
