【摘要】 实验证明,在超导微桥的桥区铌膜中注入硼离子,控制桥区铌膜的转变温度,弱化超导微桥的临界电流,是一种行之有效的方法。适当调整注入离子的能量和剂量,可以将微桥的临界电流降低2～3个数量级。更多还原

【Abstract】 Experiments show that Boron ion implantation in niobium films is an effective method for weakening critical current of superconducting bridges. By properly adjusting the energy and does of the implanted ions, the critical current of bridges can be decreased in two and even three orders of magnitude.更多还原
