Abstract Although Raman spectroscopy is a good tool for effective assessment of atomic boron concentration in diamond, determination of further physical properties using this non-destructive approach requires advancement in Raman analysis. In this work, we present an extended study of the Raman spectrum of boron-doped diamond, over a broad boron doping range and at increasing measurement temperature, based on the interaction between phonon and electronic Raman scattering effects. The presented analysis demonstrates the considerable contribution of electronic Raman scattering to the Raman spectrum and opens a practical route toward determination of additional boron-doped diamond properties, such as carrier concentration and carrier mobility.

重硼掺杂金刚石拉曼光谱分析的新视角

摘要 虽然拉曼光谱是有效评估金刚石中原子硼浓度的好工具，但使用这种非破坏性方法确定进一步的物理特性需要拉曼分析的进步。在这项工作中，我们基于声子和电子拉曼散射效应之间的相互作用，在较宽的硼掺杂范围内和增加的测量温度下对掺硼金刚石的拉曼光谱进行了扩展研究。所呈现的分析证明了电子拉曼散射对拉曼光谱的巨大贡献，并为确定额外的掺硼金刚石特性（如载流子浓度和载流子迁移率）开辟了一条实用途径。
