Effect of thermal inhomogeneity for THz radiation from intrinsic Josephson junction stacks of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$

Itsuhiro Kakeya, Yuta Omukai, Minoru Suzuki +2

Terahertz radiation from the mesa structures of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ is detected in samples with thin electrodes $<100$ nm. In samples with thick electrodes $\simeq$ 400…
