What is a diode made of?

Semiconductor diodes are constructed of layer of N-Type semiconducting material joined to a layer of P-Type semicondictor material. Beteen these is a depletion layer that varies in thickness depending of the voltage bias across the diode.

How does the structure of a diode relate to its circuit symbol?
