Abstract: We study analytically and numerically a problem of self-heating in small mesa structures. Our results show that self-heating is proportional to a characteristic in-plane size of the mesa. Experimental data for small high-T[sub c] superconductor Bi2212 mesas are in qualitative agreement with our calculations. We estimate self-heating in Bi2212 mesas with different sizes and demonstrate that self-heating can effectively be obviated in small mesa structures. © 2001 American Institute of Physics.
