TRANSMISSION ELECTRON-MICROSCOPY INVESTIGATION OF THE MORPHOLOGY OF INP STRANSKI-KRASTANOW ISLANDS GROWN BY METALORGANIC CHEMICAL-VAPOR-DEPOSITION

We have used transmission electron microscopy to determine the morphology of InP Stranski–Krastanow islands in GaInP, grown by metalorganic chemical vapor deposition at 580 °C. We investigated both capped and uncapped islands. It was found that the fully developed islands have the principal shape of truncated pyramids with a hexagonal base both before and after overgrowth. The planes defining the islands are of {001}, {110}, and {111} types. The base dimensions are 40–50 nm and 55–65 nm in the [1̄10] and [110] directions, respectively, and the height is 12–18 nm.
