Current crowding
text:
Current crowding is a nonuniform distribution of current density through a conductor or semiconductor, especially in the vicinity of electrical contacts and over PN junctions. Current crowding is one of the factors limiting the efficiency of light-emitting diodes. Materials with low mobility of charge carriers are especially prone to current crowding phenomena. It is the dominant loss mechanism in some LEDs, where the current densities, especially around the P-side contacts, reach an area of the
