- 1. J. Appl. Phys. 101, 023516 (2007) , “Effect of screw dislocation density on optical properties in n-type wurtzite GaN”, Jeong Ho You and H. T. JohnsonThe effect of open-core screw dislocations on photoluminescence in n-doped wurtzite GaN epilayer is studied computationally and compared with experimental data. A k•p Hamiltonian calculation domain is set up to contain a dipole of open-core screw dislocations, and its size... (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)
- 4. Phys. Rev. B 43, 6569 (1991) , “Optically detected magnetic resonance of dislocations in silicon”, V. Kveder, P. Omling, H. G. Grimmeiss, Yu. A. OsipyanThe observation of optically detected magnetic resonance (ODMR) signals directly correlated with dislocations in silicon is reported. The ODMR signals are identified as resonances from free electrons, dangling bonds, and quasifree holes bound to a one-dimensional potential in straight dislocations.... (Read more)
- 5. 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 <τ<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 τ, 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).
