Abstract
The characteristics of multiple-island single-electron chains are analyzed theoretically in relation to the design parameters, the materials, the background charge, and the environmental temperature with the aid of a model developed on the basis of the solution of the Poisson equation and the Monte Carlo method. It is shown that the main parameter which determines the temperature stability of the phenomenon of the Coulomb blockade is the potential-barrier height for tunneling junctions. The investigations of three systems of materials (Co-Al-O, Au-Al2O3, and Cr-Cr2O3) take shown that the multiple-island single-electron chains based on Co-Al-O are most preferable at the operating temperature. The chains based on Cr-Cr2O3 are less preferable.
