injection current. Pulsed electrical injection leads to pulsed emision from the dot, with a single photon in each pulse, provided that the pulse width is much less than the exciton lifetime. The second order correlation function recorded for theXlinewithapulsewidthof400ps(Fig,ZB(i)) shows a strongly suppressed peak at zero time delay, indicating a strong suppression of the multi-photon emission pulses from the dot. This contrasts with the pair correlation recorded for the wetting layer electroluminescence (Fig.

Standardized reporting, template proformas and perhaps dedicated gastrointestinal pathologists may improve reporting of surgical rectal cancer specimens.
