论文摘要
The generic 1-bond:2-mode percolation type Raman signal inherent to the short bond of common (A,B)C semiconductor mixed crystals with zincblende (cubic) structure is exploited as a sensitive mesoscope to explore how various ZnSe-based systems engage their pressure-induced structural transition (to rock-salt) at the sub-macroscopic scale with a focus on ZnCdSe.区分短键的AC-和BC样环境的拉曼双峰是对压力的反应：它要么关闭（Znbese，Znses）或打开（ZnCDSE）（ZnCDSE），这取决于在压力下的两个环境的硬化速率。因此概述了II-VI和III-V混合晶体的分区。特别感兴趣的是封闭情况，其中系统在其特殊点上共鸣稳定了恒星过渡，与形成拉曼双线的两个振荡器对应于虚拟脱钩，通过阻尼过度抑制。在此限制下，沿链条链条的短物种的链连接键将其冻结成刚体的骨架。这揭示了合金背后的能力以降低导热率。
The generic 1-bond:2-mode percolation type Raman signal inherent to the short bond of common (A,B)C semiconductor mixed crystals with zincblende (cubic) structure is exploited as a sensitive mesoscope to explore how various ZnSe-based systems engage their pressure-induced structural transition (to rock-salt) at the sub-macroscopic scale with a focus on ZnCdSe. The Raman doublet, that distinguishes between the AC- and BC-like environments of the short bond, is reactive to pressure: either it closes (ZnBeSe, ZnSeS) or it opens (ZnCdSe), depending on the hardening rates of the two environments under pressure. A partition of II-VI and III-V mixed crystals is accordingly outlined. Of special interest is the closure case, in which the system resonantly stabilizes ante transition at its exceptional point corresponding to a virtual decoupling, by overdamping, of the two oscillators forming the Raman doublet. At this limit, the chain-connected bonds of the short species (taken as the minor one) freeze along the chain into a rigid backbone. This reveals a capacity behind alloying to reduce the thermal conductivity.
