在表面的共振辅助，热电子诱导的飞秒化学处理（HEFATS）的理论已经发展的非弹性电子散射通过负分子离子形状共振与吸附在固体表面上的分子。两个例子，一个涉及一个宽波段的激光激发的热电子和其他可调窄带产生的固态隧道结，被用来说明潜在的HEFATS在化学键断裂，例如，在解吸。
A theory of resonance-assisted, hot-electron-induced femtochemical processing at surfaces (HEFATS) has been developed in terms of inelastic electron scattering via negative-molecular-ion shape resonances associated with molecules adsorbed on solid surfaces. Two examples, one involving a broad band of laser-excited hot electrons and the other a tunable narrow band produced by a solid state tunnel junction, are used to illustrate the potential of HEFATS in chemical bond breaking as, for instance, in desorption.
