Abstract
Intersubband resonances and collective intraband plasmon resonances are the elementary dynamic excitations of a two-dimensional electronic system. By applying uniaxial stress to a Si(100) metal-oxide-semiconductor system we can tune and energetically match the two resonances. In the crossing regime we find a resonant interaction of the two excitations leading to an enhancement of the intersubband resonance amplitude and a splitting of the dispersion.Keywords
