The transition from tunneling to contact is investigated by detecting light emitted from Au(111) in a scanning tunneling microscope. Optical spectra reflect single and multielectron processes and their distinct evolutions as a single-atom contact is formed. The experimental data are analyzed in terms of plasmon excitation and hot-hole processes.
通过在扫描隧道显微镜中检测从Au(111)发射的光，研究了从隧穿到接触的转变。光谱反映了单电子和多电子过程及其在形成单原子接触时的不同演变。根据等离子体激元激发和热空穴过程对实验数据进行了分析。
