We report the capacitance-voltage (CV) characteristics of multi quantum wells Schottky diode. This diode is based on Aluminum gallium arsenide, which is highly promising wide band gap semiconductor for applications in high power electronic and optoelectronic devices. The elaboration process and the characterization phase have been carried out at Nottingham University. The CV characteristics have been measured at different temperature ranging from 20 to 400 K. The barrier height and effective density were than extracted from 1/(C/A)2 plot using heuristic algorithm which called ALO (Ant Lion Optimizer). The accuracy of the extraction method is verified through the gotten results.
