Abstract

Quality Bi-2212 films were grown using a combined sedimentation-deposition, liquid phase sintering and annealing process. Through XRD and SEM, a film was chosen for device fabrication. Wet chemical etching process was developed to pattern weak link junctions on MgO substrate. Effects of HCl etchant solution on the constriction of the device were investigated as a function of time.
