Abstract :
Double quantum well with ¿doped lattice-strain GaAs/InGaAs/GaAs pseudomorphic heterostructures have been fabricated for the first time. Very high carrier density of more than 1Ã1013cm¿2 along with enhanced mobility of 2100 cm2/vs at 300K are achieved. Influence of barrier thickness on the carrier densities and mobilities are also investigated.
