Color centers in silicon have recently gained considerable attention as a single-photon source [1,2] and as a spin qubit-photon interface [3] for quantum information applications. However, one of the major bottlenecks is their low overall brightness due to

We synthesized and studied color centers on silicon-on-insulator wafers with photoluminescence mapping and spectroscopy, and fabricated silicon W- and G- color center LEDs towards electrically-pumped single photon sources.

We compare the suitability of various magnesium-based liquid metal alloy ion sources (LMAIS) for scalable focused-ion-beam (FIB) implantation doping of GaN. We consider GaMg, MgSO4•7H2O, MgZn, AlMg, and AuMgSi alloys. Although issues of oxidation (GaMg)
