- 論文の詳細を見る
Cathodoluminescence (CL) spectra and monochromatic CL images of GaAs/AlGaAs self-standing nanowires were observed using a transmission electron microscope combined with a CL detection system. Individual nanowires were resolved in monochromatic CL images, and the CL spectra taken from those wires by focused beam illumination showed emission peaks at different energies. Double peaks were sometimes observed to appear in the CL spectrum from a single nanowire. From the line-scan spectrum measurement and CL image observation of tilted angle illumination, it was found that a quantum-dot-like structure is formed along the nanowire.
