Three-dimensional wavelength-scale confinement in quantum dot microcavity light-emitting diodes
We introduce a microcavity light-emitting diode (LED) structure that uses submicrometer oxide aperture and a quantum dot active region to achieve strong three-dimensional confinement of both the carrier distribution and the optical field. Light-current curves show optical emission for devices as sma...
