Abstract

Using high-rc grain boundary Josephson junctions (GBJJs) made of YBa2Cu,O7.s deposited across silicon bicrystal boundary, we successfully demonstrated direct response at frequency as high as 2.525THz and the operation temperature up to 70K. Also, the effects of response on polarization of electromagnetic waves and the harmonic mixing properties are investigated. It is found that there is no polarization dependence of the response for our high-quality GBJJs. This result is favorable to the spectroscopy application. At frequency as high as 2.525THz, the high-order harmonic mixing at zero and finite bias voltage has been demonstrated.
