Abstract
(InAs)(n)/(GaAs)(m) (n =1.5-2, m = 0.25 monolayer) fractional monolayer sup erlattices (FMS) have been used to grow highly strained InGaAs quantum well s (QWs) on InP by molecular beam epitaxy. We show that FMS quantum wells ha ve better structural and optoelectronic properties compared to equivalent Q Ws grown using standard procedures. In addition, the onsets of the three-di mensional growth mode and plastic relaxation are delayed, which allows the highest emission wavelength in the InxGa1-xAs/InGaAlAs/InP system to be ext ended up to 2.35 mu m at high growth temperatures (500 degrees C).
