In a recent paper, we derived a self-consistent theory of the steady-state electron distribution of a metal under continuous wave illumination which treats thermal and non-thermal effects on the same footing. Here, we re-derive the main analytical results of that study from very simple arguments, and draw a series of conclusions which contradict claims made in previous studies of the steady-state distribution. In particular, we show that the faster chemical reactions reported in many previous papers are extremely unlikely to originate from high energy non-thermal electrons. Instead, the faster reactions very likely originate from a purely thermal effect.

协助金属纳米颗粒进行光催化–仅是经典的热源

在最近的一篇论文中，我们推导了连续波照射下金属稳态电子分布的自洽理论，该理论在相同的基础上处理热效应和非热效应。在这里，我们从非常简单的论证中重新得出该研究的主要分析结果，并得出一系列结论，这些结论与先前关于稳态分布的研究中的主张相矛盾。特别是，我们表明，以前许多论文中报道的更快的化学反应极不可能源自高能非热电子。相反，更快的反应很可能源自纯粹的热效应。
