Abstract:Quality of GaN LEDs is closely related to the defects in quantum wells. Effectively evaluating the performance of LEDs is a key step in mass production. Electrical characterization testing is very effective for characterizing the performance of LEDs, and the I-V curve is an important evaluation parameter. In this paper, we analyzed correlation in photoluminescence (PL) spectra and I-V curves among different LEDs and studied the feasibility of using PL to predict and estimate the characteristics of the I-V curv… Show more
