Abstract

Disclosed herein is a semiconducting nanoparticle comprising a one-dimensional semiconducting nanoparticle having a first end and a second end; where the second end is opposed to the first end; a first node that comprises a first semiconductor; where the first node contacts a radial surface of the one-dimensional semiconducting nanoparticle producing a first heterojunction at the point of contact; and a second node that comprises a second semiconductor; where the second node contacts the radial surface of the one-dimensional semiconducting nanoparticle producing a second heterojunction at the point of contact; where the first heterojunction is compositionally different from the second heterojunction.
