- 1. Phys. Rev. Lett. 88, 205502 (2002) , “Metastability of Amorphous Silicon from Silicon Network Rebonding”, R. Biswas, B. C. Pan, and Y. Y. YeWe propose a network rebonding model for light-induced metastability in amorphous silicon, involving bonding rearrangements of silicon and hydrogen atoms. Nonradiative recombination breaks weak silicon bonds and generates dangling bond–floating bond pairs, with very low activation energies. The... (Read more)
- 2. Thin Solid Films 395, 266-269 (2001) , “Charge-trapping defects in Cat-CVD silicon nitride films”, T. Umeda, Y. Mochizuki, Y. Miyoshi and Y. NashimotoWe show that Cat-CVD silicon nitride films contain more than 1019 cm−3 nitrogen-bonded Si dangling bonds, similarly to the case for conventional CVD films. However, the charge-trapping behavior of the Cat-CVD films is found to be quite different, in spite of the same origin for the dominant... (Read more)
- 3. Mater. Sci. Eng. B 73, 60-63 (2000) , “EPR study of He-implanted Si”, B. Pivac, B. Rakvin, R. Tonini, F. Corni and G. OttavianiElectron paramagnetic resonance has been used to study the influence of thermal treatments on defect evolution in helium-implanted Czochralski single-crystal silicon. It is shown that the thermal treatment induces helium migration and capturing by vacancy clusters that transform into pressurized... (Read more)

OttavianiElectron paramagnetic resonance spectra of S2 paramagnetic center in Float zone silicon (FZ-Si) and Czochralski silicon (CZ-Si) produced by H+2 ion-implantation and by subsequent annealing have been studied. At room temperature the spectrum exhibits an isotropic line g=2.0066±0.0002, which,... (Read more)
- 5. Phys. Rev. Lett. 85, 2324-2327 (2000) , “Fast Diffusion of H and Creation of Dangling Bonds in Hydrogenated Amorphous Silicon Studied by in situ ESR”, U. K. Das, T. Yasuda, and S. YamasakiThe interaction of atomic hydrogen with a-Si:H films was studied by means of in situ ESR during H plasma treatment. H diffuses into the a-Si:H film and creates additional Si dangling bonds (∼1013 cm -2). We observed a high diffusion coefficient (>10-10  cm... (Read more)

Tanaka.A variety of electron-spin-resonance (ESR) spectra of dangling bond (g=2.0055) in undoped hydrogenated amorphous silicon (a-Si:H) have been measured by the echo-detected ESR of pulsed ESR as well as the usual continuous-wave (cw) ESR for a wide range of two experimental parameters of microwave...

- 8. 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)

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)

TitleThe g values, line shapes, and linewidths of the ESR signals from within the bulk of amorphous silicon, germanium, and silicon carbide are found to be similar to those of the electron states observed in the surface regions of the corresponding crystalline forms. Discussion is given in terms of a... (Read more)Ge Si SiC| EPR| Carbon D Germanium Silicon amorphous dangling-bond .inp files: Si/amorphous | last update: Takahide Umeda

Haneman.EPR measurements have been made on aligned cleavage faces of Si, prepared and studied in high vacuum (<10-9 Torr). The signal, observable after accumulation, is a single line at g=2.0055 with width 6 G, similar to that from vacuum-crushed powders. It is unaffected by oxygen exposures... (Read more)
