Radiation damage, defects and surfaces
Surface Science, 1979Abstract The status of radiation damage and defects in bulk metallic, covalent and ionic systems is reviewed, including damage production processes, defect configurations and defect migration mechanisms. These results are then considered in the vicinity of a surface. The physical surface and the electronic surface can alter bulk defect processes, but

Radiation annealing of defects under the effect of γ-radiation
Journal of Nuclear Materials, 1996Abstract With the neutron and gamma spectra and the ratio of their intensities taking place in fission reactors, neutrons predominantly create defects which are annealed by γ-quanta. These main characteristics of irradiation vary in different reactors as well as results of their influence on irradiating materials.

RADIATION INDUCED DEFECTS IN BIPOLAR POWER TRANSISTORS: INFLUENCE OF RADIATION ENERGY
Astroparticle, Particle and Space Physics, Detectors and Medical Physics Applications, 2004The results of a study on the radiation-induced defects in a bipolar power transistor exposed to electrons of different energies are reported. The devices have been irradiated with electron beams of energies ranging from 2.2 up to 8.6 MeV and different doses from 0.2 to 5 × 10^13 electrons/cm2 (0.8-25 kGy).

Radiation-Induced Defects in Radiation Hard and Soft Oxides
Acta Physica Sinica (Overseas Edition), 1994The point defects of Pb and E' in radiation hard and soft Si-SiO2 samples were examined using electron spin resonance (ESR). The experimental results showed that these defects were correlated with the ways of oxidation process, the dosage of 60Co radiation and the radiation bias field.

The effect of dislocations on the formation of radiation defects in silicon
physica status solidi (a), 1982The effect of dislocations introduced at plastic deformation (ND = 1 × 105 to 2 × 107 cm−2) on the radiation defect production and annealing processes in n- and p-type Si single crystals (g = 20 to 1500 ω cm) irradiated (Tirr ≦ 320 K) by γ-rays of 60Co or 640 MeV protons is studied.

Defects and radiation damage in metals
Journal of Nuclear Materials, 1969M. W. Thompson London: Cambridge University Press. 1969 Pp. viii + 384. Price £6 Prof. Thompson has written a book in which the ideas and material are presented at two quite distinct levels of scientific sophistication. In the first quarter of the book he discusses the nature of point and extended defects in crystals at an extremely elementary level ...

Radiation Defects in LiBaF3 Perovskites
2000We investigated the electron paramagnetic resonance (EPR), recombination afterglow, thermostimulated luminescence (TSL) and absorption of LiBaF3 perovskites crystals X-irradiated at 80 K The self-trapped hole centre VK(F2-) oriented along the [110] axis and electron F type (FA) centres are identified.

Radiation damage and point defects
Philosophical Magazine, 2013Sir Alan Cottrell has made huge seminal contributions to our basic understanding of radiation damage processes in both fissile and non-fissile materials. Much of this ground-breaking work was accomplished in the mid-1950s when Cottrell was working at Birmingham University and later at Harwell Laboratory. It is interesting to relate the earlier progress
