Abstract:
1. A semiconducting nanoparticle comprising: a one-dimensional nanoparticle having a first end and a second end, where the second end is opposed to the first end; a first endcap at each of the first end and the second end, wherein the first endcaps comprise a first semiconductor; and a second endcap at each of the first end and the second end, wherein the second endcaps comprise a second semiconductor and partially or completely encircle the first endcaps at each of the first end and the second end; wherein each of the first endcaps contacts a surface of the one-dimensional nanoparticle at each of the first end and the second end producing a first heterojunction at each of the points of contact; wherein the second endcap at the first end contacts a surface of the first endcap at the first end, producing a second heterojunction at the point of contact, and the second endcap at the second end contacts a surface of the first endcap at the second end producing a second heterojunction at the point of contact; wherein the first heterojunction is compositionally different from the second heterojunction.
