独立电子表面跳跃(IESH)是一种计算方法,用于计算金属表面分子运动中的非绝热电子跃迁。IESH适用于强耦合的情况下,电子摩擦模型是可疑的,并已被证明可以准确地再现详细的分子束实验的结果,从(111)表面的金的一氧化氮的振动非弹性散射。然而,在其原始形式中,IESH代表了一个封闭的系统,没有明确包括衬底原子的局部区域之外的能量流。在本文中,我们提出了两个“恒温器”引入能量流的散装,一个声子和其他电子激发。
Independent Electron Surface Hopping (IESH) is a computational method for accounting for nonadiabatic electronic transitions in simulations of molecular motion at metal surfaces. IESH is applicable in cases of strong coupling where the electronic friction model is suspect, and has been demonstrated to accurately reproduce the results of detailed molecular beam experiments on vibrationally inelastic scattering of nitric oxide from the (111) surface of gold. However, in its original form, IESH represents a closed system without energy flow outside the local region of explicitly included substrate atoms. In this paper we propose two "thermostats" for introducing energy flow to the bulk, one for phonons and the other for electronic excitations.
