EDS and EXAFS spectroscopy are used as complementary techniques to investigate the local structure of bimetallic ultrathin nanowires. Results highlight the importance of using a combined approach to achieve an accurate understanding of these systems.

In terms of understanding and tuning the optoelectronic behavior within functional devices, quantum dot (QD)-based heterostructures represent an excellent model system and opportunity for analyzing exciton dissociation and charge separation across a well-defined nanoscale interface.
