Trends in hot carrier distribution for disordered noble-transition metal alloys.

We developed and tested an approach for predicting trends for efficient hot carrier generation among disordered metal alloys. We provide a simple argument for the importance of indirect transitions in the presence of disorder, thus justifying the use of joint density of states ()-like quantities for exploring these trends. We introduce a new-like quantity,, which heuristically accounts for longer lifetimes of quasiparticles close to the Fermi energy.
