摘要：

Low frequency noise properties of all-thin film superconductor-constrictions-superconductor devices have been investigated. We first found that the magnitude of 1/f noise level rapidly decreases with increasing the device quality factor Q(-1) and saturates for Q(-1)greater than or equal to 2. From Hooge theory [1] this saturation phenomena indicates that the number of carriers in the system no longer changes for Q(-1)greater than or equal to 2.
