Electron spin resonance studies of hydrogenated amorphous boron (a-B:H)


Journal Article

The electron spin resonance of hydrogenated amorphous boron produced by the direct current glow discharge of diborane in hydrogen was studied and the effects of annealing on the signal intensity and linewidth are reported. The resonance in the unannealed sample indicated a composite line arising from two centers, one of which predominates at room temperature. The predominate line has a g-factor of 2.083 and a peak-to-peak linewidth of 130 G which is essentially independent of temperature below 25°C. From the low temperature behavior of the linewidth we estmate the spin-spin relaxation time to be 5×10-10 s. At higher temperatures Raman processes seem to dominate since the spin-lattice relaxation time varies as T-2. © 1982.
