- 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. Appl. Phys. Lett. 89, 044107 (2006) , “Photoluminescence imaging of silicon wafers”, T. Trupke, R. A. Bardos, M. C. Schubert, and W. WartaPhotoluminescence imaging is demonstrated to be an extremely fast spatially resolved characterization technique for large silicon wafers. The spatial variation of the effective minority carrier lifetime is measured without being affected by minority carrier trapping or by excess carriers in space... (Read more)

Lett. 89, 041916 (2006) , “Photoluminescence evaluation of defects generated during SiGe-on-insulator virtual substrate fabrication: Temperature ramping process”, Dong Wang, Seiichiro Ii, Hiroshi Nakashima, Ken-ichi Ikeda, Hideharu Nakashima, Koji Matsumoto, and Masahiko NakamaeCrystal qualities of Si/SiGe/Si-on-insulator structures with different SiGe thicknesses were evaluated by photoluminescence (PL). The wafers were annealed at different temperatures with a ramping rate of 5 °C/min. Free exciton PL peaks were clearly observed for the as-grown wafers and decreased... (Read more)

Phys. 100, 114303 (2006) , “Influence of paramagnetic defects on multicolored luminescence from nanocrystalline silicon”, Keisuke Sato and Kenji HirakuriWe report on the correlation between paramagnetic defects and the luminescent properties of nanocrystalline silicon (nc-Si) using electron spin resonance (ESR) and photoluminescence measurements. Nanocrystalline silicon having particle sizes from 1.9 to 3.0 nm exhibited continuous luminescence... (Read more)

Davies, J. Tan, P. G. Coleman, C. P. Burrows, and J. Wong-LeungDefect centers generated in crystalline silicon by MeV Si implants have been investigated by a combination of photoluminescence, variable-energy positron annihilation measurements, depth profiling by etching, annealing studies, and the dependence on impurities. The broad 935 meV photoluminescence... (Read more)

Cardona, K. M. Itoh, H. Riemann, N. V. Abrosimov, M. F. Churbanov, A. V. Gusev, A. D. Bulanov, A. K. Kaliteevskii, O. N. Godisov, P. Becker, H.-J. Pohl, J. W. Ager III, and E. E. HallerWe resolve the remarkably sharp bound exciton transitions of highly enriched 28Si using a single-frequency laser and photoluminescence excitation spectroscopy, as well as photocurrent spectroscopy. Well-resolved doublets in the spectrum of the 31P donor reflect the hyperfine... (Read more)

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)

Tichelaar, P. F. A. Alkemade.Experimental studies of size-related effects in silicon nanocrystals are reported. We present investigations carried out on nanocrystals prepared from single-crystal Si:P wafer by ball milling. The average final grain dimension varied depending on the way of preparation in the range between 70 and... (Read more)

Langhanki, J. –M. SpaethN-type silicon doped with gold and lithium was investigated by Electron Paramagnetic Resonance (EPR) and Deep Level Transient Spectroscopy (DLTS), using two sets of samples with different defect concentrations of both gold and lithium.

OsipyanThe observation of optically detected magnetic resonance (ODMR) signals directly correlated with dislocations in silicon is reported.

- 12. Physica B 116, 583-593 (1983) , “Investigations of well defined dislocations in silicon”, H. Alexander, C. Kisielowski-Kemmerich, E. R. WeberThe velocity v of dislocation half-loops introduced into swirl-free floating-zone grown undoped silicon has been measured at 420°C in the resolved shear stress range 30 <Ï„<300 MPa. Clearly impurity atoms interact with dislocations in this material. Using the starting value of v we found the two types of 60° dislocations, which are distinguished by the sequence of their partials, to have different velocities. Furtheron the velocity depends not only on Ï„, but also on the elastic strain of the lattice. In the second part the papers review EPR spectroscopy of plastically deformed silicon and collects new results on the activity of dislocations in this material as trapping / recombination centers (decay of photo-EPR, photoluminescence, EBIC microscopy and photoplastic effect).

The stress splitting of the Raman line results from a twofold splitting of the... (Read more)
