Finally, measurements of excess electron-hole recombination rates by time-resolved techniques show lifetimes less than 10 ns in these quantum wells.doi:10.1016/0039-6028(86)90423-1W. GoltsosJ. NakaharaA.V. NurmikkoD.L. PartinElsevier B.V....
However, the electron–hole pair may undergo recombination, leading to a decrease in the photocatalytic efficiency of semiconductors. Photocatalytic production of hydrogen from water using semiconductors as photocatalysts is one of the main strategies for converting sunlight into chemical energy. Cadmium ...

aAs we know, the substitution of O2 ions by F ions could influence the energy band structure of BiVO4 and act as electrons and holes traps by altering the photogenerated electron–hole pairs recombination rate. In detail, the photogenerated holes were trapped by surface lattice oxygen atoms, res...
The electron–hole pair has a broad distribution of initial electron and hole energies; only two are shown for clarity. (b) Optical excitation of an electron in the metal directly into the CB of the semiconductor through the DICTT pathway. (c) The newly demonstrated PICTT pathway, where ...
