Popis: This work reports on the approach of metamorphic In(Ga)As quantum wells on GaP/Si(001) substrates for Si-based mid-infrared applications. Metamorphic InP and In0.83Al0.17As templates are grown on Si, and room temperature photoluminescence emissions at 2.1 μm and 2.6 μm have been demonstrated from InAs/In0.53Ga0.47As triangular quantum wells and InAs quantum wells on the templates, respectively. The surface root mean square roughness is 4-5 nm. The quantum wells act fully strained and the threading dislocation density is 107-108 cm-2 in the upper side of buffer.
