Nanowires for single photon detection and spin memory devices

Objective

The ultimate limit in the miniaturization of electronics and photonics is at the nanometer scale. Here the signal level can be controlled at the fundamental level of a single electron and a single photon. These limits are actively being pursued for scientific interest with possible applications in the area of quantum information processing and communication. We propose novel devices aimed at single photon detection and single spin memory using nanowires. The basic building block is a III-V quantum dot defined in a Si nanowire. We will develop the following technology: (1) growth of complex semiconductor nanowire, (2) quantum state storage and transfer onto a photon state for the memory device, and (3) single photon detection and electron multiplication for single photon detection. The nanowires will be grown by the vapor-liquid-solid mechanism. The structures and devices obtained after growth and each nanofabrication steps will be thoroughly characterized and the final test devices performances will be evaluated.
