In situ detection of radiation and heat balance in large Bi2212 mesas
Artikel i vetenskaplig tidskrift, 2010

We use small Bi2212 mesas for in situ detection of THz radiation from the large mesas at high bias at which Joule heating is important. We numerically analyze the heat balance in the emitter mesas taking into account anisotropy and temperature dependencies of all parameters involved in the heat transport. The mesa temperature is spatially non-uniform and can exceed Tc in the middle part of the mesa. The non-uniform temperature distribution can be important for synchronization of radiation from the intrinsic Josephson junctions.
