P. Wahlgren et al., HORIZON PICTURE FOR THE ELECTRODYNAMIC ENVIRONMENT OF COULOMB-BLOCKADE DEVICES, Czechoslovak journal of Physics, 46, 1996, pp. 2765-2766
The influence of a low impedance electromagnetic environment on Coulom
b blockade of tunneling can be explained and qualitatively estimated t
hrough a simplified horizon picture, where the environment is reduced
to a voltage dependent capacitance. We have studied the offset voltage
, V-off, for three different circuit layouts. The measurements are wel
l explained by the horizon picture.
