A comparison of the electronic differential cross sections computed with this model with other theories and experimental data reveals that the influence of the electron-ion correlation is more significant for low energy emitted electrons. 展开
and the electrons surrounding them are long-lived particles present in all ordinary, naturally occurring atoms. Other subatomic particles may be found in association with these three types of particles. They can be created only with the addition of enormous amounts of energy, however, and are ver...
It grows with hydrogen atom incidence energy and exhibits an energy-loss onset equal to the Ge surface bandgap. This leads us to conclude that hydrogen atom collisions at the surface of a semiconductor are capable of promoting electrons from the valence to the conduction band with high efficiency...

Single-atom precious metal catalysts hold the promise of perfect atom utilization, yet control of their activity and stability remains challenging. Here we show that engineering the electronic structure of atomically dispersed Ru1 on metal supports via c
Single-atom alloys have recently emerged as highly active and selective alloy catalysts. Unlike pure metals, single-atom alloys escape the well-established conceptual framework developed nearly three decades ago for predicting catalytic performance. Although this offers the opportunity to explore so far ...
The structures of amides resemble those of other carbonyl compounds: the three atoms bonded to carbon are in the same plane (Figure 12.3). The nitrogen atom of an amide has an unshared pair of electrons that is delocalized with the π electrons of the carbonyl group. An amide, such as fo...
Finally, we describe methods used to measure the spin-polarization of electrons from a limited number of atom layers on surfaces, focusing on the current status of our development of the RHEED-Mott spin detector hybrid method. 关键词: Electron spin-polarization Top atomic layer of solid surfaces...
