Atom-based Quantum Research
a) Sample fabrication. A thick silicon on insulator (SOI) sample is implanted with carbon ions and recrystallized by annealing at high temperature. By optical lithography and chemical etching, membranes are formed and then SiN is deposited. b) Scanning electron micrograph (SEM) of SOI membranes before SiN deposition. c) SEM of a strained SOI membrane with SiN on top. d) Photoluminescence spectra from an ensemble of G-centers as a function of the membrane size.
