Abstract: Amorphous silicon carbide may be doped with one or more ions such as vanadium and these ions may radiate light if excited, for example, using optical or electrical pumping. A single photon light source may be formed from a single such ion that is pumped or from a plurality of ions that are pumped if light from only one ion is collected, e.g., using an aperture or pin hole. Such single photon sources may possibly be use in quantum computing, quantum sensing and/or quantum telecommunications.

Abstract: Additive color mixing across the visible spectrum was demonstrated from a light emitting diode (LED) pixel comprising of red, green, and blue subpixels monolithically integrated and enabled by local strain engineering. The device was fabricated using a top-down approach on a metal-organic chemical vapor deposition-grown sample consisting of a typical LED epitaxial stack. The three color subpixels were defined in a single lithographic step. The device was characterized for its electrical properties and emission spectra under an uncooled condition, which is desirable in practical applications. The color mixing was controlled by pulse width modulation and the degree of color control was also characterized.
