Fabrication of the weak link with the the Transistor Characteristics in 77 K

77K에서 트랜지스터 특성을 나타내는 링크의 제작

The link for the Superconducting Flux Flow Transistor (SFFT) which is based on the flux flow has been fabricated by the ICP etching methods. The channel width and the thickness of the SFFT were a 3 ${\mu}$m and about 300 nm, respectively. The superconducting characteristic of the link was measured by the x-ray diffraction and the E.D.S.. The SFFT etched by ICP showed an I-V characteristic like the three terminal transistor.
