AbstractSelf-organization of two-dimensional InN nucleation islands into chains along the 112̄0 directions is revealed by scanning tunneling microscopy (STM). Such alignments occur on surfaces of InN(0001) with GaN insertion layers below, i.e., in InN/GaN/InN sandwich-structures. Increasing the temperature of nucleation leads to a reduced degree of ordering of the islands. For nucleation on surfaces of homogeneous and strain-free InN films, on the other hand, randomly distributed islands are observed. The possible origin of the island-chain formation is discussed. © 2011 Elsevier B.V. All rights reserved.
