There have been a lot of Spice diode models which account for charge 
storage developed.  Most if not all of them concentrate on PIN diodes 
but I'm sure the same modeling techniques would apply to non PIN diodes. 
  Search in the IEEE journals related to power electronics if you're 
interested (an example is http://ieeexplore.ieee.org/document/349750/).

Papers aren't _my_ problem... I have several dozen on the subject.  I
have developed a fairly simple modeling method that seems robust.  All
I need is data from specific devices to test my method.

What's the mechanism for forward overshoot?  All those electrons and

Probably ;-}

Actually it _is_ diffusion as Phil points out.

However that doesn't mean it's not modelable with Spice... as he
WRONGLY asserts.

Caught them napping.

We built a 2KV pulse generator that uses a silicon diode in
Grehkov/DSRD mode.

We applied 48 volts in the forward direction, and waited for the diode
to conduct. The current rose linearly to about 100 amps in maybe 80
ns, still at +48. Then we applied -400 through a small inductor. The
diode reverse conducted, basically shorted, for 50 ns or so as the
reverse current increased, then suddenly opened, when the stored
charge was depleted. The voltage twanged to -1KV for 2 or 3 ns, and we
doubled that with a transmission line.

The trick here is to forward bias the diode briefly, before the
carriers drift all over the place and pollute the junction. The HP1430
sampler (a 12 GHz oscilloscope in 1965) used a similar trick: forward
bias a step-recovery diode for a few ns to make the reverse snap
faster.
