PY 1994 BP 1981 EP 1982 VL 235-240 DI 10.1016/0921-4534(94)92212-8 DE YBCO HTS switches AB A transition of YBCO bridge 60 nm thick from superconducting to normal state induced by an abrupt current step has been studied. A subnanosecond stage has been observed during both S-N and N-S transition. The data obtained can be explained by hot-electron phenomena. On the basis of experimental results a prediction of picosecond switch performance has been made. ER
