摘　　要：文章给出了高Ｔｃ超导红外探测器的理论分析；器件设计．并报道了用ＧｄＢａ２Ｃｕ３Ｏ７－ｘ薄膜制备的红外探测器的实验结果。得到的最好结果是噪声等效功率ＮＥＰ（５００，１０，１）＝１．４×１０－１１ＷＨｚ－１／２；探测率Ｄ（５００，１０，１）４．２×１０９ｃｍＨｚ１／２Ｗ－１；响应度Ｒｖ＝１０６５Ｖ／Ｗ．Abstract A theorctical analysis and design are given for a bolometric infrared detector that uses the resistive transition of a high temperature superconducting thin film as the temperature sensing element, and liquid nitrogen (LN) as the coolant. It is shown that for highly oriented c-axis GdBa2Cu3O7- film, the noise equivalent powers NEP(500, 10, 1) =1. 4×10-11WHz-1/2; the normalized detectivity D*=4.2×109 cmHz1/2W-1 ; the responsivity Rv(500, 10, 1) =1065V/W were the best results.
