AlGaAs AQW
Asymmetric quantum well structure
GaAs/GaAlAs/GaAs Asymmetric Quantum Wells (AQW) serving as the basis for advanced electro-optical devices have shown multiple advantages in the domain of inter-sub-band transitions. ALEO’s new approach enables the creation and modulation of self-induced electrical fields as a function of the varying dopant concentration in the structure. We have performed numerical and analytical analyses towards these structures’ future integration in advanced devices.
