| Research Abstract |
Objective of this research is to establish the growth technique for compound semiconductor nanowires for applications in lasers, single photon emitters and solar cells. I establish the growth technology to form quantum dot structures embedded in nanowires and processing technology for nanowire-based optoelectronic devices. I characterize the optical and device characteristics of the devices utilizing nanowire-quantum dots. I observe single-photon emission process from high-quality single nanowire-quantum dot by means of auto-correlation measurements. I propose and demonstrate a growth scheme to form highly uniform, multi-stacked quantum dots embedded in nanowires and achieve high quality multi-stacked nanowire-quantum dots up to 200 layer without degradation of the optical properties. In addition, we demonstrate optoelectronic devices including lasers, single photon emitters and solar cells utilizing nanowire-quantum dots.
