Beschreibung:

We present far-infrared (FIR) photoconductivity measurements for a two-dimensional electron gas in an array of nanostructured antidots. We detect, and resistively and spectrally resolve, both the magnetoplasmon and the edge-magnetoplasmon modes. Temperature-dependent measurements demonstrate that both modes contribute to the photoresistance by heating the electron gas via resonant absorption of the far-infrared radiation. Influences of the spin effect and phonon bands on the collective excitations in the antidot lattice are observed. © 2003 The American Physical Society.
