J.C. Fenton, G. Yang, C.E. Gough
TL;DR
This study uses high-resolution IV measurements on 2212-BSCCO mesa structures to investigate the effects of heating and nonequilibrium phenomena on c-axis quasiparticle conductivity.
Contribution
It demonstrates that heating significantly influences IV measurements, highlighting the importance of considering thermal effects in such experiments.
Findings
Heating effects dominate IV measurement results
High-resolution measurements reveal thermal influence
Nonequilibrium effects are less significant
Abstract
We report four-point IV measurements of the c-axis conductivity of mesa structures of 2212-BSCCO, using a system with sub-microsecond resolution along with multi-level pulses. These allow a test to be made for the presence of nonequilibrium effects. Our results suggest simple heating alone is important in measurements of this kind.
