A PNP configuration has three layers of germanium semiconductor material. These layers are doped to create two P-type layers on either side of an N-type layer. The P-type layers have an excess of positively charged holes, while the N-type layer has an excess of negatively charged electrons.

The transistor has three terminals - the emitter, base, and collector. The emitter is heavily doped to create a large number of charge carriers, while the base is lightly doped to allow for control of the transistor's operation. The collector is moderately doped to facilitate the collection of charge carriers.

When a small current flows from the base to the emitter, it creates a larger current flow from the collector to the emitter. This is due to the transistor's ability to amplify and control current. By controlling the current at the base, the transistor can effectively switch the larger current flow from the collector on and off.

Germanium transistors were widely used in early electronic devices, such as radios and televisions, due to their ability to work with low power levels. However, they were later replaced by silicon transistors, which offered better performance and reliability.
