Plasmon Excitations in Thin Metal Films. Transition from Three‐Dimensional to Two‐Dimensional Behaviour

Density oscillations are studied within the infinite-barrier model. Intersubband and intrasubband modes are characterized with respect to their frequency, spatial amplitude field, and collective nature. Special attention is paid to particular limiting cases in terms of the length scales defined by slab thickness and excitation wavelengths. Im Rahmen des „Infinite-Barrier”-Modells werden Dichteschwingungen untersucht. Intersubband- und Intrasubband-Moden werden bezuglich ihrer Frequenz, ihrem raumlichen Amplitudenfeld und ihrer kollektiven Natur charakterisiert. Besondere Aufmerksamkeit wird dabei speziellen Grenzfallen, definiert durch die Langenskalen der Schichtdicke und der Anregungswellenlange, gewidmet.
