Popis: | The authors report the growth of quaternary ZnCdSeTe nanotips and ZnSe/ZnCdSeTe superlattice nanotips on oxidized Si(1 0 0) substrate. It was found that the nanotips exhibit mixture of cubic zinc-blende and hexagonal wurtzite structures. It was also found that photoluminescence intensities observed from the ZnSe/ZnCdSeTe superlattice nanotips were much larger than that observed from the homogeneous ZnCdSeTe nanotips. Furthermore, it was found that activation energies for the ZnSe/ZnCdSeTe superlattice nanotips with well widths of 12, 16, 20, and 24 nm were 189, 205, 292, and 240 meV, respectively. |
