Cyclotron resonance and the magnetophonon effect in GaxIn1−xAsyP1−y
TLDR
In this article, the effective mass as a function of alloy composition for GaxIn1−xAsyP1−y samples grown lattice matched to InP was measured using cyclotron resonance and magnetophonon effect.Abstract:
Cyclotron resonance and the magnetophonon effect have been used to measure the effective mass as a function of alloy composition for GaxIn1−xAsyP1−y samples grown lattice matched to InP. Values of ωτ of up to 6 allow an accurate measurement of effective mass, which is found to depend linearly upon alloy composition y with the relation m*/m0=0.080−0.039y. The observation of shallow impurity transitions in a quaternary alloy is also reported.read more
