The study of the evolution of the conduction band in dense gases and supercritical fluids near the critical point has been complicated by a lack of precise experimental measurements. Both photoemission from an electrode immersed in the fluid and field ionization of a molecule doped into the fluid have been used to probe solvent density effects on the energy of an excess electron as a function of fluid number density and temperature. In this perspective, we present recent experimental results that show a strong critical point effect on the minimum conduction band energy near the critical density and temperature of a fluid. We also discuss the recent development of a new theoretical model that advances our understanding of the density and temperature dependence of the conduction band minimum in near critical point fluids.
