Low-Dimensional Systems


The influence exerted by a nonlinear electromagnetic wave on the dc conductivity of a superlattice is analyzed. An essentially nonlinear current-voltage (I-V) characteristic is obtained. A portion of negative absolute conductivity appears in the I-V characteristic at certain nonlinear-wave parameters. A distinction is made between the given case and that of a monochromatic wave, when a large number of such portions may exist. For typical superlattice parameters, some of the negative absolute conductivity must appear at a nonlinear wave field strength E0≈1.8×103 V/cm.
