中文摘要	We have developed an Ar ion-beam-assisted technique for preparing YBa2Cu3O7 (YBCO) bicrystal junctions with the apropos critical current, high normal resistance and high characteristic voltage. The dependence of the critical current and normal resistance of YBCO bicrystal junctions on the ion beam energy and annealing temperature has been investigated. By using this technique, junctions with normal resistance R-n up to 3-8 Omega and characteristic voltage IcRn of 200-720 mu V have been obtained. In addition, the scaling relation of the characteristic voltage with the critical current has been examined, which is in good agreement with the results obtained by other researchers. An infrared detector was fabricated by the YBCO bicrystal junction with high normal resistance of 6 Omega and characteristic voltage of 720 mu V. The obtained maximum responsitivity of the detector was up to 220 V/W at 77 K. Its noise equivalent power (NEP) at 78 K was of 9.0 x 10(-13) W/root Hz. (C) 1997 Elsevier Science B.V.
