- W2185588289 abstract "Josephson junctions are produced by electron beam irradiation of pattemed YBa2Cu307-6 thin film tracks on MgO substrates. Single weak links show Fraunhofer type critical current behaviour as a function of field (Ic(H)), indicating reasonable current uniformity across the junction. Simple low inductance SQUIDs have also been made with >70% critical current modulation at 25K. The relatively high critical current density of these weak links means that it is possible to observe a cross-over from small to large junction behaviour at a temperature only a few degrees below the Tc of the junction. In the small junction regime the current-voltage (IV) curves can be fitted by the resistively shunted junction (RSJ) model, whilst in the large junction regime the IV curves change to be non-RSJ like. The IcRn product is typically around 0.05 - 0.2 mV at temperatures a few degrees below the Tc of the junction and for a junction with a high T, can reach 1mV at 4.2K. The width of the irradiated line is found to be in the range 20-100nm. I. INTRODUCTION A large number of approaches have been taken to produce Josephson junctions in the high Tc materials with some of the most successful to date being the bi-crystal grain boundary junction (l), edge junctions (2),(3), edge junctions with a barrier (4) Y-ZrO2 bi-crystal substrates (5) and many others. The aforementioned references all have in common Fraunhofer like Ic(H) for single junctions indicating good uniformity across the junction. The successful use of ion irradiation to produce SQUIDs in high-Tc materials has also been reported (GI. In this paper we report on the successful production of Josephson junctions and a simple type of SQUID by electron beam irradiation, whose primary advantage over a technique such as ion irradiation is the smaller spot size of around lnm. This method is successful with the high-T, materials because the low atomic mass of the oxygen makes it possible for electrons of moderate energies to overcome the -18eV binding energy and displace the oxygen." @default.
