Current crowding (also current crowding effect, or CCE) 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 (e.g., aluminium gallium indium phosphide (AlGaInP)) are especially … WebThis new approach to current spreading in quasi-vertical diodes avoids excessive current flow, field crowding, and premature breakdown at the mesa edges. It does this by improving electrical current uniformity in group III-nitride devices with thin current spreading layers (CSL). By sandwiching a thin gallium nitride (GaN):beryllium (Be) i-layer thin film … farnborough medical lecture society
