High-frequency hopping conductivity and permittivity in compensated semiconductors

In semiconductors, high-frequency conductivity is caused by polarization re versal of the collective states of a pair of impurity atoms under the actio n of the random electric fields of all the impurities. A Coulomb correlatio n which appreciably increases the conductivity is established as a result o f the statistical distribution of the particles over four levels of the dia tomic system. The relaxation absorption and the permittivity of the entire pair system are calculated allowing for these statistics. (C) 2000 MAIK "Na uka/ Interperiodica".
