Fabrication of good quality YBCO/STO/YBCO multilayers by using an ArF excimer laser deposition technique

ArF excimer laser 증착 기술을 이용한 우수한 특성의 YBCO/STO/YBCO 다층 박막 제작

High temperature superconductor shows a good electric and magnetic properties and is known as a good candidate in various electronic device application. At present the technique to construct multilayers composed of HTS films and insulator films has not been fully studied in domestic research institutes. Since the construction of any reasonable eletronic devices require the use of multilayers, the development of HTS eletronic devices has been limited. To manufacture multiplayer, several processing steps which involve deposition and ion millings are required. To manufacture a good quality multilayerd structure, not only the deposition techniques but also the proper patterning have to be developed. In this work, we have fabricated a YBCO/STO/YBCO multiplayer and studied the electronic properties of it.
