The diode ideality factor (A), reverse saturation
current density (Jo), and shunt conductance for the
junction performance are extracted from the dark J–V
curve. Fitting to the ln(J)–V data for the forward bias
between 0.5 and 0.8 V gives an approximately linear
and yield diode ideality factor, A, of 2.49 and a Jo of
1.2 10–7 A/cm2. From the slope of the J–V characteristic
at a zero bias, the shunt conductance is estimated to
be 2.39 10–4 (S/cm2), which corresponds to a shunt
resistance of 4,184 Ω/cm2.
