ELECTRON SPIN RESONANCE STUDIES OF SELECTED SOLIDS.
Abstract
Electron spin resonance experiments on shallow donors in germanium are reported. The experiments consist in measurement of the Zeeman effect of the donors as a function of applied /110/ compression. From the data a value may be derived for the valley-orbit (singlet-triplet) splitting (4Dc) of the donor ground state. The results for P donors agree with determinations by other workers. The result for Sb in Ge is 4Dc = (4.04 = 0.1) x 0.0001 ev. This result is not consistent with the value obtained from piezo-resistance measurements. The data also require that the singlet state lie below the triplet in Sb-donors, just as in P and As donors. An additional four-line spin resonance spectrum in Sb-doped Ge is ascribed to donors located near the surface of the samples, in regions of high local strain. Studies concerning proton polarization in polyethylene targets are also reported. (Author)
