Abstract

Light-emitting diode emission behaviors at a very weak injection current level are studied using the photon-counting method. It is observed that the emission is superlinearly dependent on the injection current irrespective of the emitting wavelength. The bending point of the L:I plot is different from that of the V:I plot. The bimolecular emission nature is interpreted to be a nonradiative transition mechanism due to some deep level trapping.
