Correlation between Al grain size, grain boundary grooves and local variations in oxide barrier thickness of Al/AlO(x)/Al tunnel junctions by transmission electron microscopy
A thickness variation of only one Ångström makes a significant difference in the current through a tunnel junction due to the exponential thickness dependence of the current. It is thus important to achieve a uniform thickness along the barrier to enhance, for example, the sensitivity and speed of s...
