TL;DR: In this article, the authors demonstrate that coherent continuous-wave terahertz (THz) radiation of sizable power can be extracted from intrinsic Josephson junctions in the layered high-temperature superconductor Bi 2 Sr 2 CaCu 2 O 8.
Journal ArticleDOI
Direct observation of tetrahertz electromagnetic waves emitted from intrinsic Josephson junctions in single crystalline Bi2Sr2CaCu2O8+δ

TL;DR: In this article, a single crystalline mesa structure of the high-T c superconductor Bi 2 Sr 2 CaCu 2 O 8+ δ intrinsic Josephson junction system was fabricated by the Argon-ion-milling and photolithography techniques on the cleaved surface of a single crystal.
Journal ArticleDOI
Geometrical Resonance Conditions for THz Radiation from the Intrinsic Josephson Junctions in Bi 2 Sr 2 CaCu 2 O 8 + δ
Manabu Tsujimoto,Kazuhiro Yamaki,K. Deguchi,Takashi Yamamoto,Takanari Kashiwagi,Hidetoshi Minami,Masashi Tachiki,Kazuo Kadowaki,Richard A. Klemm +8 more
TL;DR: The integer higher harmonics observed in all spectra imply that the ac Josephson effect plays the dominant role in the novel dual-source radiation mechanism.
Journal ArticleDOI
Broadly tunable subterahertz emission from internal branches of the current-voltage characteristics of superconducting Bi2Sr2CaCu2O(8+δ) single crystals.

TL;DR: Continuous, coherent subterahertz radiation arises when a dc voltage is applied across a stack of the many intrinsic Josephson junctions in a Bi2Sr2CaCu2O(8+δ) single crystal.
Journal ArticleDOI
Characteristics of terahertz radiation emitted from the intrinsic Josephson junctions in high-Tc superconductor Bi2Sr2CaCu2O8+δ
TL;DR: In this paper, a terahertz radiation emitted from a rectangular mesa comprised stacked intrinsic Josephson junctions in the layered high-Tc superconductor Bi2Sr2CaCu2O8+δ is reported.
