摘　　要：本文报道了高温超导体ＴｌＢａＣａＣｕＯ外延膜的微波（３６ＧＨｚ）辐照响应特性．在超导转变温区附近，其响应行为基本属于辐射热效应．在Ｔ＝１０７Ｋ附近，其微波响应率可达８．１４Ｖ／Ｗ，等效噪声功率ＮＥＰ约９．１５×１０－１１Ｗ／Ｈｚ．实验结果表明，该类器件可望用于宽带电磁辐射检测．Abstract: The microwave(36GHz) response behavior of films of TlBaCaCuO was reported. The epitaxial results show that the bolometric component of the microwave response was dominant at the vicinity of T c (107K). As a possible application in radiation detection,the responsitivity of the device is about 8.14V/W and NEP is about 9.15×10 -11 W/Hz.
