TokmoldinRecent deep level transient spectroscopy (DLTS), electron paramagnetic resonance (EPR) and infrared (IR) spectroscopy data on interactions of self-interstitial with carbon, aluminium, oxygen and hydrogen in silicon irradiated by light ions are reviewed. Self-interstitial behaviour in silicon was... (Read more)

Gorelkinskii.The behavior of self-interstitials in silicon which was irradiated with light ions (protons and -particles) and electrons was explored by monitoring known impurity interstitial centers (Ci, Ali, (Si-O)i) with deep level transient spectroscopy (DLTS) and electron...

GorelkinskiiAn electron-paramagnetic resonance (EPR) study of proton-irradiated silicon has revealed two new EPR spectra labeled Si-AA13 and Si-AA14. Spectrum AA13 has C3v symmetry (g = 1.9985 and g = 2.0024 ± 0.0002), AA14 C1 symmetry. These spectra correspond to positive (B+) and negative (B−)... (Read more)

Gorelkinskii.A new metastable complex in monocrystalline silicon irradiated at with protons has been studied. Electron paramagnetic resonance (EPR) Si-AA13 ( symmetry) and Si-AA14 ( symmetry) spectra as well as the known Si-A18 spectrum originate from different molecular configurations of the complex. A...

Suprunchik.Investigation of the defect formation in heavily doped silicon irradiated by high dose of electrons have led to the discovery of new types of defects /1, 2/. The present note is the next one of this series. A new centre is investigated in p-type silicon irradiated by neutrons.

- 6. Phys. Rev. B 14, 872-883 (1976) , “EPR of a <001> Si interstitial complex in irradiated silicon”, K. L. Brower.This paper deals with an electron-paramagnetic-resonance study of the Si-B3 center, which was first reported by Daly. The Si-B3 center is a secondary defect which forms upon annealing between 50 and 175°C in irradiated boron-doped silicon and is stable up to ?500°C. Our studies indicate that the... (Read more)

CorbettThe Si-P6 spectrum shows an intrinsic tetragonal symmetry with the C2 axis along ?100? and distortion forces the principal axes of the g tensor to be displaced in the {100} plane. The g tensor previously identified by Jung and Newell was found to be due to the motionally averaged state... (Read more)
- 8. Lattice Defects in Semiconductors 23, 1-22 (1975) , Institute of Physics, London , “EPR Studies of the Lattice Vacancy and Low-Temperature Damage Processes in Silocon”, G. D. Watkins.EPR studies of silicon irradiated at 20.4 K and 4.2 K by 1.5 MeV and 46 MeV electrons are described. In 46 MeV irradiations the dominant defects formed appear to be divavancies and other multiple defect aggregates which liberate vacancies throughout the anneal to room temperature as they reorder, recombine, etc. For 1.5 MeV irradiations group III atoms play a vital role in p- and n-type materials in trapping interstitials and stabilizing damage. Carbon and oxygen are not effective interstitial traps at these temperatures. Evidence of limited vacancy migration during irradiation is also cited. Two distinct excited configurations of vacancy-oxygen pairs are identified as precursors to A-centre formation in n-type silicon. The kinetics for their conversion to A-centres depends strongly upon the Fermi level as does the isolated vacancy migration energy whhich is measured to be 0.18 ± 0.02 eV for the Vï¼ charge state. The vacancy has four charge states, V+, V0, Vï¼ and Vï¼. Kinetics for hole release from V+ reveals an activation barrier of 0.057 eV. The concentration of V+ at 20.4 K in boron-doped material indicates the corresponding donor level even closer to the band edge, approximately EV + 0.039 eV. Jahn-Teller energies for V0, V+, and Vï¼ are estimated from stress-alignment studies and confirmed to be large. Kinetics studies for reorientation from one Jahn-Teller distortion to another are also described for each charge state.
