Diode Sensitivity (IMAGE) Moscow Institute of Physics and Technology Caption Dependence of diode sensitivity on alternating current frequency for various values of angle φ. The main graph corresponds to a direct current intensity at 99 percent of the critical value. On the inset, DC intensity is zero.
