| 英文摘要 | Porous silicon (ps) treated by water vapor annealing and vacuum annealing has been studied by positron annihilation lifetime spectroscopy and age-momentum correlation measurement. it is found that after water vapor annealing, non-radiative defects are reduced and defects dominating light source appear. these two types of defects change the lifetime and the s parameter of the positron annihilation and cause a drastic enhancement in the photoluminescence (pl) efficiency. defects that cause the pl of ps show no obvious change after annealing at 300 degrees c in vacuum, therefore the pl of the sample is not influenced. |
