- Supported by the Royal Society under the URF scheme and a DTG from the EPSRC this collaboration between University of Leeds and SHU used the atomistic semiempirical pseudopotential method to explain fast biexciton decay times and large optical gaps in InSb colloidal quantum dots. The findings were that the s-like symmetry of the valence band maximum in In-rich and Sb-rich structures, leads to a failure of the band edge absorption converging to the bulk band. The Auger-like nature of the extremely fast biexciton decay, suggests the possibility of intriguingly high carrier multiplication yields in this system.
