One aspect of the invention involves an article of manufacture that includes a dielectric layer with an array of pores, and an array of nanowires at least partially contained within the array of pores. A respective nanowire in the array of nanowires is formed within a respective pore in the array of pores. Nanowires in the array of nanowires include a core semiconducting region with a first type of, a shell semiconducting region with a second type of doping, and a junction region between the core semiconducting region and the shell semiconducting. Additionally, the article of manufacture includes a first conducting layer electrically coupled to a plurality of shell semiconducting regions for a plurality of nanowires in the array of nanowires, as well as a second conducting layer electrically coupled to a plurality of core semiconducting regions for a plurality of nanowires in the array of nanowires. |
