Alessio brings in the first publication of 2016: Indium Phosphide Quantum Dots

The collaboration between the Cossairt and Li groups at UW boasts a new publication in The Journal of the American Chemical Society. For the first time the crystallographic structure of a “magic-sized” nanocluster, an important class of intermediates at the interface of small molecules and quantum dots, has been resolved. The obtained structure deviates from […]

How to describe XAS transition properties

Patrick and Franco have recently published a paper showing how to properly describe the quadrupole-allowed transitions that can be probed with X-ray Absorption Spectroscopy (XAS). Different commonly used schemes to describe transition properties were compared and their respective faults and merits were detailed. One scheme is origin dependent and violates the Thomas-Reiche-Kuhn sum rule for […]

Imaging Excited Orbitals with STM

Working with Prof. Martin Gruebele at the University of Illinois, we showed that it is possible to capture nanometer resolution images of electronically excited PbS quantum dots, using a combination of single molecule absorption and scanning tunneling microscopy (SMA-STM). Usually STM can only image ground state electron density. Transient or steady-state absorption spectroscopy can access […]
