TEMPERATURE-DEPENDENCE OF CONDUCTANCE IN SERIALLY CONNECTED ONE-DIMENSIONAL RINGS

The temperature dependence of quantum oscillations has been studied in serially connected one-dimensional ballistic rings. For magnetostatic Aharonov-Bohm (AB) conductance oscillations, the width of the Fabry-P erot peak decreases as the number of connected rings increases at a fi xed temperature. For electrostatic AB conductance at a finite temperat ure, the amplitude of the electrostatic conductance oscillations decre ases as the electrostatic potential increases. However, the amplitude decreases very slowly as the number of rings increases.
