Properties of small HTSC mesa structures: common problems of interlayer tunneling

Abstract

I analyze common problems of interlayer tunneling in Bi-2212 mesa structures, such as self-heating and nonuniformity of junctions. Numerical simulations have shown that self-heating does not mask the temperature dependence of the superconducting gap. Major problems can be avoided by decreasing mesa sizes.
