(a) Experimental setup for (a) time-resolved microtransient lens (TR-M-TL) and (b) near-field scanning optical microscopic transient lens (NSOM-TL).
Typical time profile of the TR-M-TL signals taken for the .
Results of the numerical calculations. (a) Time-dependent special distribution of the transient lens. (b) Time profiles of the carrier lens, thermal lens, and total transient lens signals. (c) Spot size dependence of the time profiles of the transient lens signals.
(a) NSOM-photoluminescence (NSOM-PL) and (b) NSOM-TL images for QW. The scanning area is . The regions surrounded by the black and white dotted lines are radiative and nonradiative recombination centers, respectively.
Schematics of the diffusion and recombination carrier dynamics as observed in Fig. 4.
