✦ Synopsis

The conductivity anisotropy and high-frequency properties of a two-dimensional superlattice (SL) with a non-additive electron dispersion law in the presence of a strong static electric field are studied theoretically. The main effort was a search for mechanisms allowing realization of the high-frequency negative differential conductivity in the range with positive static differential conductivity.
