文摘

The multiple peak photoluminescence corresponding to the contributions of the individual quantum wells formed in the nanowire shell was observed. The surface depletion potential, the intrinsic electron concentration and the actual widths of the quantum wells and the barriers formed in the nanowire shell were determined. The presented data suggest formation of highly uniform cylinder symmetry two-dimentional quantum wells embedded in the nanowire shell. We demonstrate that the reported results show a possibility to use the radial heterostructure shell of self-assembled nanowire array as a building block of electronic and optoelectronic devices.
