摘要: 從許多文獻中得知超導量子干涉元件對磁場具有極高的靈敏度,可當作磁場對電壓輸出的轉換元件,本篇論文是以高溫超導釔鋇銅氧、磁控濺鍍系統、黃光微影製程、乾式濕式蝕刻以及10 mm×10 mm雙晶基板SrTiO3,在晶界上產生類似絕緣層的S-I-S穿隧機制,製作出具有高靈敏度的超導量子干涉元件,元件有效面積約為0.14 mm2,在77 K的時候觀察到此時超導量子干涉元件具有約10μΦ0/Hz1/2和14μΦ0/Hz1/2左右的磁通雜訊在1 KHz,換算後得到SB1/2約為147 fT/Hz1/2和207 fT/Hz1/2
From past literature we know superconductor quantum interference device (SQUID) is the most sensitive to detect magnetic field in the world. It can be use as a voltage-flux transfer device. Here we grow high temperature superconductor YBa2Cu3O7-x thin film on bicrystal substrate by magnetron sputter system, and use photolithography, ion milling, and wet etching to fabricate our SQUID.After that we measure R-T, I-V and V-T data at 77 K. Finally, a flux noise of approximately 10μΦ0/Hz1/2 and 14μΦ0/Hz1/2at 77 K at 1kHz has been archived, from which calculate the magnetic field sensitivity of 147 fT/Hz1/2 and 207 fT/Hz1/2 is available.
