Abstract :
Atomic ordering and decomposition of InxGa1-xAsyP1-y grown lattice matched on InP(001) is investigated with cross-sectional scanning tunnelling microscopy. The atomic composition of the quaternary material is analyzed at both the (110) and (110) cleavage surfaces, yielding two different decomposition effects on different length scales: a formation of columnar structures with widths amounting to some tens of nm and a CuPt-like ordering on the atomic scale.
