Ana Cros Vibrational properties of semiconductor nanowires and nanowire heterostructures: ensembles and single nanowires physica status solidi (RRL) - Rapid Research Letters 7
Part of Focus Issue on “Semiconductor Nanowires” (Eds.: Chennupati Jagadish, Lutz Geelhaar, Silvija Gradecak)
Semiconductor nanowires present intriguing new vibrational phenomena related to their elongated shape, phonon mode confinement and electron phonon coupling. The interest of these properties, together with the large amount of material data that can be accessed through the analysis of phonon modes, place Raman spectroscopy as a necessary tool for the characterization of these nanostructures. This review gives a brief snapshot of the state-of-the-art in Raman spectroscopy and imaging of nanowire ensembles and individual nanowires.
