Charge Offset and Noise in SET Transistors



Neil M. Zimmerman, J. L. Cobb


We report on several previous and ongoing investigations into the source of, and the amelioration of, the charge offset noise in SET (single-electron tunneling) transistors, made of Al/AlOx/Al tunnel junctions. Previous work has shown that significant time-dependent noise will arise from locations outside the tunnel junctions, as well as within the junctions. Our ongoing work includes attempts to reduce or eliminate the charge offset and noise in fabricated devices.
