Growth of metamorphic InGaP layers on GaAs substrates
Artikel i vetenskaplig tidskrift, 2013

We report on the growth of InGaP metamorphic layer by gas source molecular-beam epitaxy. After optimization of the growth temperatures of the compositionally graded InGaP layer and the indium content in the top metamorphic InGaP layer, almost fully relaxed metamorphic layer was obtained with surface roughness of only about 2.17 nm. Strong photoluminescence signals were measured from both InGaAs quantum well and InAs quantum dots embedded in the metamorphic layer, indicating that the top metamorphic layer had low density of threading dislocations.
