摘要
A strained In0.40Ga0.60P/In0.2Ga0.8As/GaAs pseudomorphic high electron mobility transistor structure (PHEMT) was proposed to improve the electron transport properties. The structures were grown by the solid source molecular beam epitaxy (SSMBE) technique. With the incorporation of a strained In0.40Ga0.60P barrier layer and a GaAs smoothing layer, higher Hall mobility was achieved, indicating that better electron distribution was formed in the proposed structure. Photoluminescence (PL) measurements verified that the incorporation of a strained barrier and a smoothing layer into the PHEMT structure modifies the electron distribution so that most of the electrons are distributed in the In0.2Ga0.8As channel, resulting in high electron mobility.
