    wavelengths on InP(111)A

## Description

- description: "We demonstrate the formation of InAs quantum dots (QDs) on InAlAs/InP(111)A
    by means of\r\ndroplet epitaxy. The C_3v symmetry of the (111)A substrate enabled
    us to realize highly symmetric\r\nQDs that are free from lateral elongations.
    The QDs exhibit a disk-like truncated shape with\r\nan atomically flat top surface.
    Photoluminescence signals show broad-band spectra at telecommunication wavelengths
    of 1.3 and 1.5 μm. Strong luminescence signals are retained up to\r\nroom temperature.
    Thus, our QDs are potentially useful for realizing an entangled photon-pair source
    that is compatible with current telecommunication fiber networks."
