- 71. Phys. Rev. B 33, 4471 (1986) , “Strain broadening of the dangling-bond resonance at the (111) Si-SiO2 interface”, K. L. BrowerIt is observed that the linewidth and line shape of the Zeeman resonance associated with dangling bonds at the (111)Si-SiO2 interface (Pb centers) vary with the direction of the applied magnetic field. An analysis of the line shape of this resonance indicates that it can be... (Read more)

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)

Sci. 141, 255-284 (1984) , “X AND K BAND ESR STUDY OF THE Pb INTERFACE CENTRES IN THERMALLY OXIDIZED p-TYPE (001)Si WAFERS AT LOW TEMPERATURES AND INFLUENCE OF MEDIUM-DOSE As+ ION IMPLANTATION”, A. Stesmans, J. Braet, J. Witters, R. F. DekeersmaeckerElectron spin resonance (ESR) experiments have been carried out at cryogenic temperatures (4.2 T 35 K) and room temperatures at 9.0 and 20.9 GHz on the Pb0 and Pb1 (commonly referred to as Pb) spin-active defects residing at the Si/SiO2 interface. The ESR lineshapes were shown to display gaussian... (Read more)

BrowerThe hyperfine spectrum associated with unpaired electrons at the (111) Si/SiO2 interface (Pb centers) is reported for the first time. Electron paramagnetic resonance measurements indicate that the hyperfine interaction S··I arises from the... (Read more)

R. RazoukInterface states and electron spin resonance centers have been observed and compared in thermally oxidized (111) and (100) silicon wafers subjected to various processing treatments. The ESR Pb signal, previously assigned to interface ·SiSi3 defects on (111)... (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)

Voget-GroteAmorphous SiOx-layers with O < x < 2 have been prepared by evaporation of Si at oxygen pressures of 10−6 … 10−3 mbar. The composition of the samples was determined by proton backscattering. The band gap, derived from optical measurements, increases with rising oxygen... (Read more)

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)

NishiThree kinds of paramagnetic centers named PA, PB and PC have been found in a silicon-silicon dioxide structure at liquid nitrogen temperature. PA (g=∼2.000, ΔH=∼4 Oe), and PB having anisotropic g-value... (Read more)
- 80. 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.
