Abstract
Substantial progress has been made in recent years in fabricating complex axial and radial nanowire heterostructures. In these structures the band structure can be modified through cubic and hexagonal polytypes, strains caused by lattice mismatch, or quantum confinement in core multi-shell structures. Understanding exactly how the electronic properties of the nanowire are changed in these heterostructures requires spectroscopies with high spatial, temporal and spectral resolution. I will discuss a series of examples of how novel optical spectroscopies can provide insights into changes in electronic structure within a single nanowire.
Coffee and tea will be served 20 minutes prior to the seminar.
