Publisher: | Institute of Electrical and Electronics Engineers Inc. | Abstract: | Rectangular intrinsic Josephson junction mesa structures of superconducting Bi2Sr2CaCu2O8+delta (Bi2212) can be used as a source of continuous, coherent and polarized terahertz (THz) radiation. THz emitting mesas are below a certain underdoped level of Bi2212. They have small Josephson critical current in contrast to optimally doped and overdoped Bi2212. We deposited Au/Co/Au multilayer top of mesa and obtained small critical current from mesas fabricated by as-grown Bi2212 single crystals due to injection of spin polarized current. The spin injection eliminates adjustment of doping level for successful THz emission. | Description: | Workshop on Terahertz and Mid Infrared Radiation (TERA-MIR 2009) | URI: | https://hdl.handle.net/11147/10059 | ISBN: | 978-1-4244-3848-8 |
