Wavelength and polarization variations of InAs/GaAs quantum dots emission at liquid Helium temperature via microphotoluminescence spectroscopy

In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

The effect of doping Graphene Quantum Dots with K, B, N, and Cl on its emitted spectrum

In this work, the effect of doping Graphene Quantum Dots (GQDs) on their emission spectra has been studied. First, graphene has been deposited on SiC substrate by using sublimation method. Second, doped-GQDs have been distributed on the surface of graphene via drop casting. The structure of the samples have been studied and characterized by X-ray diffraction (XRD), Scanning Electron Microscopy ...

Deep ultraviolet to near-infrared emission and photoresponse in layered N-doped graphene quantum dots.

Material that can emit broad spectral wavelengths covering deep ultraviolet, visible, and near-infrared is highly desirable. It can lead to important applications such as broadband modulators, photodetectors, solar cells, bioimaging, and fiber communications. However, there is currently no material that meets such desirable requirement. Here, we report the layered structure of nitrogen-doped gr...
