Sarma, DD (1989) Electronic structure of high Tc cuprates by electron spectroscopies. In: NATO ASI Series, Series C: Mathematical and Physical Sciences, 276 . pp. 499-507.Full text not available from this repository.
Electron spectroscopic techniques were used to show that the ground state of high TC cuprates is primarily described in terms of mixed valency between 3d9 and 3d10-related configurations, with very little Cu3+(3d8) configuration. Temp. dependent changes in the special features are interpreted in terms of formation of dimerized hole species in primarily oxygen p-derived band, while Cu concomitantly assumes a larger proportion of 3d10 related configuration. The formation of these dimerized hole species leads to a drastic decrease in the frequency dependent surface resistivity of the samples.
