@article { , title = {Compositional variations in In0.5Ga0.5N nanorods grown by molecular beam epitaxy}, abstract = {The composition of InxGa1 ? xN nanorods grown by molecular beam epitaxy with nominal x = 0.5 has been mapped by electron microscopy using Z-contrast imaging and x-ray microanalysis. This shows a coherent and highly strained core-shell structure with a near atomically sharp boundary between a Ga-rich shell (x?0.3) and an In-rich core (x? 0.7), which itself has In- and Ga-rich platelets alternating along the growth axis. It is proposed that the shell and core regions are lateral and vertical growth sectors, with the core structure determined by spinodal decomposition.}, doi = {10.1088/0957-4484/25/21/215705}, eissn = {1361-6528}, issn = {0957-4484}, issue = {21}, journal = {Nanotechnology}, publicationstatus = {Published}, publisher = {IOP Publishing}, url = {https://nottingham-repository.worktribe.com/output/729280}, volume = {25}, keyword = {InGaN nanorods, transmission electron microscopy, molecular beam epitaxy, EDX mapping, core-shell structures, spinodal decomposition}, year = {2014}, author = {Cherns, D. and Webster, R.
