Time-resolved electroluminescence has been primarily and widely applied in the field of optoelectronic devices and phosphor materials. Here we use the method to measure the response time and phase difference of green light-emitting diode.
In our experiment, which is essentially dominated by pulsed signal from function generator¡Bhigh spatial resolution from laser scanning microscopic and phase-lock characteristic from lock-in amplifier to complete our experimental result. We are capable to detect relative carrier information within any point or any surface region from epi-layer of green light-emitting diode.
Otherwise, the carrier transport of the sample is able to be observed through time-resolved characteristic measurement. Laser cutting would be beneficial for obvious phase-difference observation and mobility acquirement.
