我们报告了在热退火影响下真空中直径约 1.3 nm 的初始球形金刚石纳米团簇演化过程的计算模型。当退火温度超过 1000 K 时，就会转变为可识别的手性核壳团簇。讨论了这对于星际介质的组成以及与从前太阳陨石 (Boriskino) 获得的实验拉曼散射数据的关系的影响。
We report on the computational modelling of the evolution process of initially spherical diamond nanoclusters with diameters ≈1.3 nm in vacuo under the influence of thermal annealing. The transformation into recognizable chiral core-shell clusters occurs for temperatures of annealing exceeding 1000 K. The implications of this with regard to the composition of the interstellar medium and the relationship with experimental Raman scattering data obtained from a pre-solar meteorite (Boriskino) are discussed.
