- 1. Phys. Rev. B 75, 115201 (2007) , “Atomistic modeling of the (a+c)-mixed dislocation core in wurtzite GaN”, I. Belabbas, A. Béré, J. Chen, S. Petit, M. Akli Belkhir, P. Ruterana, and G. NouetAn atomistic simulation of the threading (a+c)-mixed dislocation core in wurtzite GaN has been carried out. Starting from models generated in the framework of continuum elasticity theory, two core configurations are obtained independently by using an empirical potential and a... (Read more)

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)
- 3. Phys. Rev. B 32, 6571 (1985) , “Electrical Properties of Dislocations and Point Defects in Plastically Deformed Silicon”, P. Omling, E. R. Weber, L. Montelius, H. Alexander, J. Michel.Energy levels of defect states introduced by plastic deformation of n-type silicon have been studied by capacitance transient spectroscopy. From the observed properties of the defects, it is concluded that two different types of defects are produced. The first type is interpreted as point defects... (Read more)

OsipyanMagnetic properties of the dislocation dangling bond (DDB) spin system in silicon crystals are investigated by means of the EPR technique at T = (1.3 to 150) K. Experimental results are obtained which enable one to develop a one-dimensional model of the spin system according to which the DDB chains... (Read more)
- 5. phys. stat. sol. (a) 55, 251 (1979) , “Photo-EPR of Dislocations in Silicon”, R. Erdmann, H. Alexander.The dependence of the EPR spectrum of dislocations in deformed silicon on illumination with monochromatic light reveals the two EPR centers Si - K1 (S < 1/2) to be different ionization states of one and the same dislocation center. The energy level separating these ionization states lies near the... (Read more)
- 6. Sov. Phys. JETP 31, 677-679 (1970) , “Electron Paramagnetic Resonance in Plastically Deformed Silicon”, V. A. Grazhulis, Yu. A. Osipyan.Lightly doped silicon crystals were investigated experimentally by the electron paramagnetic resonance method. Paramagnetic centers, generated during plastic deformation of these crystals, were detected. The concentration of these centers increased monotonically with increasing degree of deformation. The EPR spectrum of these centers was anisotropic and had a partially resolved fine structure. The centers werestrongly annealed only at temperature T ≧ 600ºC and the activation energy of the annealing process was ~2 eV. It was concluded that these centers were due to electrons of broken bonds in the cores of dislocations with edge components.
