摘要：
An equivalent circuit obtained from microwave impedance and power data is proposed for a resonant tunneling diode. The four-element circuit consists of a series R and C in parallel with a nonlinear negative differential conductance -G, the combination in turn in series with a resistor r. The resistive cut-off frequency predicted by this model depends on both the RC and RG products. Detection at THz frequencies is also explained by the model.
