Simulation and analysis of radio-frequency single-electron transistor (RF-SET) by SPICE

A simulation method for a reflection-type radio-frequency single-electron transistor (RF-SET) is developed. By introducing the equivalent circuit of propagating microwaves through a coaxial cable, we solve the time-dependent master equation for BF-SETs self-consistently by using the conventional circuit simulator SPICE including the time-dependent SET current model. By examining reflected waves from a typical RF-SET, we also show that the method successfully produces clear Coulomb oscillation and reflection power strongly correlated with the SET's conductance, which is in good agreement with the experimental data published previously.
