Abstract :
A theory for intrinsic exciton spontaneous emission (radiative lifetimes) in semiconductor quantum wires is presented. Radiative decay in low-dimensional systems is fundamentally different than in the bulk where recombination must be associated with phonons, impurities, defects, surfaces, or interfaces. Radiative decay times of the order of 100 ps are presented-about an order of magnitude longer than intrinsic decay times in quantum wells. The effect of electromagnetic coupling in quantum-wire arrays is also discussed
