Abstract
Terahertz plasmons in the grating-gate FET structures with two-dimensional electron channels are investigated.
The Ohmic resistance of heterostructures with a low, but wide barrier Al0.1Ga0.9As located between two quantum well GaAs is measured at in-plane magnetic fields B=0-9 T. The resistance increases in factor of 10 at magnetic fields from 0 to 5 T and in factor of 400 at B=0-9 T.
