Abstract
We investigate the high-speed modulation characteristics of quantum dots in red emitting quantum dot-light emitting diodes, in which the -3dB cutoff frequency for 6-mm2 device is 1.5 MHz under optimized conditions. The introduction of a positive offset DC bias voltage greatly increases the modulation speed at low applied voltage range.
