Description: 
Due to a typing mistake, the pixel dwell time during the laser confocal photoluminescence (PL) and photocurrent mapping is not correct. The correct value is 64ls and not 46ls. Moreover, due to an error in the laser power calibration curve, evidenced only in recent measurements, the excitation power used during the mapping measurement was 16lW and not 4.3 lW. For this reason, the reported values of the External Quantum Efficiency (EQE) are over estimated of 3.72 times. The correct average EQE of the map in Figure 2 is then 0.094% and not 0.35%. The figures with the correct EQE scale are reported in the following Figures 2 and 4.
