Abstract
We study analytically and numerically a problem of self-heating in small me sa structures. Our results show that self-heating is proportional to a char acteristic in-plane size of the mesa. Experimental data for small high-T-c superconductor Bi2212 mesas are in qualitative agreement with our calculati ons. We estimate self-heating in Bi2212 mesas with different sizes and demo nstrate that self-heating can effectively be obviated in small mesa structu res. (C) 2001 American Institute of Physics.
