WebFeb 9, 2024 · Carriers quickly condense into excitons. In QRs, electrons within the shell contribute to a significant photoconductivity, which is reduced after electron localization within the core, followed by exciton condensation. Despite the modest localization, core electrons show a negligible contribution to the QR photoconductivity. WebEnergy–momentum diagrams showing the types of transition: (a) direct bandgap semiconductor; (b) indirect bandgap semiconductor. f Direct bandgap Semiconductor. Electrons and holes on either side of the forbidden energy gap have the. same value of crystal momentum and thus direct recombination is. possible. The energy maximum of …
