Using the photoluminescence intensity correlation method, the transient distribution of photo‐excited hot electrons under an external electric field is studied in a quasi‐one‐dimensional structure to reveal the competition of the heating effect and the cooling effect due to emission of LA and LO phonons. Temporal accumulation of carriers around the LO phonon emission threshold was achieved by heating the carriers with the external electric field.
