PN JUNCTION CONSTRUCTION - varies from one manufacturer to the next.
Some of the more commonly used manufacturing techniques are GROWN,
ALLOY or FUSED-ALLOY, DIFFUSED, and POINT-CONTACT.
CURRENT FLOW IN AN N-TYPE MATERIAL this is similar to conduction in
a copper wire. That is, with voltage applied across the material, electrons will
move through the crystal toward the positive terminal just like current flows in
a copper wire.
