Y. Ohbuchi et al., Evaluation of interface states in ZnO varistors by spectral analysis of deep level transient spectroscopy, JPN J A P 1, 38(2A), 1999, pp. 899-900
Interface states in ZnO varistors were studied using spectral analysis of d
eep level transient spectroscopy (SADLTS) to obtain the emission rate spect
rum. We found one interface state in ZnO with the activation energy and the
capture cross section distributed around their central values, E-0 = 0.98
eV and sigma(0) = 1.8 x 10(-16) cm(2), over widths Delta E = 0.19 eV and De
lta sigma = 2.9 x 10(-17) cm(2), respectively.
