Abstract:
We report a study into the process of energy transfer between quantum wells divided by $30$-nm-thick opaque barriers. It was experimentally observed that the intensity of a photoluminescence signal from a quantum well increased by $15\%$ under resonant excitation of exciton transition in the adjacent quantum well. The quantum wells were $30$ nm apart. A radiative mechanism of energy transfer in the near-field region of emitting exciton is proposed. Within this theoretical model, the efficiency of the energy transfer decreases by a power law with greater distance between the quantum wells. The theory is found to be in qualitative agreement with the experimental results.
