WebBerkeley Lab — Lawrence Berkeley National Laboratory WebAug 18, 2024 · Here is a picture: The first plot (blue) is the I-V Shockley curve for D3, whereas the second one (green) is the voltage at the node connecting D3 to R3 v/s the voltage at the node connected to D3. The two plots are slightly different, probably in the slope of the exponential curve. I have seen the Shockley equation for a diode before.

The energy of a low-angle boundary is dependent on the degree of misorientation between the neighbouring grains up to the transition to high-angle status. In the case of simple tilt boundaries the energy of a boundary made up of dislocations with Burgers vector b and spacing h is predicted by the Read–Shockley equation: where:
