Nearly ten years ago one of the MBE systems in the Braun Center was transformed to growth of semiconductor nanowires by the vapor-liquid-solid (VLS) technique.  This activity concentrating mostly on growth of InAs and GaAs nanowires and heterostructure nanowires initially concentrated mostly on understanding and improving the crystalline structure and recently encompasses a range of mesoscopic physics studies, beginning with the Cooper pairs splitting experiment and observation of the Majorana fermions related zero bias peak.
