Title:
ELECTROMAGNETIC WAVE DETECTION ELEMENT AND ELECTROMAGNETIC WAVE DETECTION DEVICE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/038706
Kind Code:
A1
Abstract:
It is possible to improve negative resistance characteristic which can be expected when an SNS (super-conductive body - normal conductive body - super-conductive body) structure is used as a configuration unit for series connection. On the top of a first super-conductive electrode, a second super-conductive electrode together with a part of its cross section is superimposed so as to sandwich an insulation film which is superimposed together with a part of its cross section. A normal-conductive line electrically connects the first and the second super-conductive electrode passing along the cross section of the insulation film, thereby constituting a configuration unit having a single weak coupling. A plurality of such configuration units are prepared which are connected in series. At the both ends of the series, the first super-conductive electrode or the second super-conductive electrode is an element connected to a pull-out line. The configuration units are arranged so that the cross sections of the insulation films along which the normal-conductive line passes are arranged in the same direction.
