| Zusammenfassung: | The detection efficiency of a newly built photon detection system was measured using photons emitted from a scanning tunneling microscope junction. The efficiency was estimated from the instrumental yield and the geometry of the system on a clean Ag(111) surface using a measured photon map and a simultaneously measured topography image. The photon generation rates of gold three-dimensional (3D) islands and two-dimensional flat layers grown on a Si(111) surface were compared, and an enhanced photon generation rate was observed for the 3D island nanostructures. |
