- W1520921666 abstract "IR reexcitation of carriers which remain metastable in a‐Si:H at low temperature after an optical excitation, induces a transient pulse on the Photoluminescence (PL) and the Photoconductivity (PC). From the PL pulse a metastable carrier density of ∼1017 cm−3 is deduced while the PC pulse shows that carriers are retrapped and reexcited ∼100 times before recombining. It is also shown that at least some of the metastable carriers are in long lifetime radiative states and that they have a logarithmic time decay. This and comparison with ESR data strongly suggests that the metastable carriers are trapped in tail states and that some tail states are radiative states for the 1.2–1.4 eV luminescence band in a‐Si:H." @default.
