In the original published paper [Appl. Phys. Lett. 89, 182121 (2006)] Fig. 1 contained an error. The orientation of the FTIRs beam splitter was falsely illustrated. The correct version of Fig. 1 is shown below. We apologize for this error.
FIG. 1.
Schematic of photomodulated infrared spectroscopic set-up. The mirrors are for PR measurement. For PT, the mirrors are removed, and the sample is rotated by 90° to perpendicular to the probe beam.
