(a) Estimated rms injected current as a function of frequency and different offsets applied and (b) EL as a function of frequency. The MOS-LED is biased by a sinusoidal waveform. The dc reference is measured with a dc bias equal to 3.66 V.
(a) (Squares) Estimated injected electrical power; (lines) CPE model fits as a function of value; (b) (dots) module of complex impedance characteristics as a function of frequency; (triangles) phase of complex impedance as a function of frequency; (lines) fit of the data by R-CPE parallel equivalent model (inset): , , and . Measurement data are for an and .
Normalized power efficiency as a function of frequency and different applied offsets; power efficiency level in dc at (horizontal dashed line), the absolute dc power efficiency is 0.05%.
