论文摘要
分离的微米大小的钻石是通过SI（001）底物上的微波血浆化学蒸气沉积技术生长的。每颗钻石都是由GA+焦点离子束在Si底物中铣削的标记唯一识别的。形态和微晶结构分析表明钻石是二十面体或双晶体。与其他水晶相比，与其他水晶相比，二十面体钻石具有更高（最高$σ_\ mathrm {h} $ = 2.3 GPA）和更宽的分布（$Δσ_\ Mathrm {h} $ = 4.47 GPA）的液压压力。分析了微钻石中纳入的SIV色中心的数量和光谱形状，并通过温度依赖性的光致发光测量和蒙特卡洛模拟来估计。 Montecarlo模拟表明，Siv-Color中心的数量为每个微钻石。
Isolated, micro-meter sized diamonds are grown by micro-wave plasma chemical vapour deposition technique on Si(001) substrates. Each diamond is uniquely identified by markers milled in the Si substrate by Ga+ focused ion beam. The morphology and micrograin structure analysis indicates that the diamonds are icosahedral or bi-crystals. Icosahedral diamonds have higher (up to $σ_\mathrm{h}$ = 2.3 GPa), and wider distribution ($Δσ_\mathrm{h}$ = 4.47 GPa) of hydrostatic stress built up at the microcrystal grain boundaries, compared to the other crystals. The number and spectral shape of SiV- color centers incorporated in the micro-diamonds is analysed, and estimated by means of temperature dependent photoluminescence measurements, and Montecarlo simulations. The Montecarlo simulations indicate that the number of SiV- color centers is a few thousand per micro-diamond.
