Enhanced luminescence from the disordered quantum-wire superlattice

The disordered quantum-wire superlattice (d-QWRSL), in which individual layer thicknesses are randomly disordered, is grown. Luminescence characteristics are investigated with changing temperature and compared with those of a conventionally ordered quantum-wire superlattice (o-QWRSL). We observe the luminescence capability enhanced by disordering the atomic arrangement. The luminescence intensity of the d-QWRSL decays gently with increasing temperature and then becomes stronger above similar to 100 K as compared with that of the o-QWRSL.
