Raman Spectroscopy in Group IV Nanowires and Nanowire Axial Heterostructures Anaya Calvo, Julián Torres, Alfredo Jiménez López, Juan Ignacio Rodríguez, Andrés Rodríguez, Tomás Ballesteros, Carmen Raman Spectroscopy The control of the SiGe NW composition is fundamental for the fabrication of high quality heterostructures. Raman spectroscopy has been used to analyse the composition of SiGe alloys. We present a study of the Raman spectrum of SiGe nanowires and SiGe/Si heterostructures. The inhomogeneity of the Ge composition deduced from the Raman spectrum is explained by the existence of a Ge-rich outer shell and by the interaction of the NW with the electromagnetic field associated with the laser beam. 2016-12-16T10:03:44Z 2016-12-16T10:03:44Z 2016-12-16T10:03:44Z 2014 info:eu-repo/semantics/article MRS Proceedings, 2014, Volume 1659, p. 143-148 http://uvadoc.uva.es/handle/10324/21797 10.1557/opl.2014.197 eng https://www.cambridge.org/ info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 International Cambridge University Press
