A pân junction. The circuit symbol is shown: the triangle corresponds to the p side. See also: pân diode and Diode Â§ Semiconductor diodes. A pân junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor.he same is true of an n-doped semiconductor, but the junction between them can become depleted of charge carriers, and hence non-conductive, depending on the relative voltages of the two semiconductor regions.
