Abstract
The authors report a very high capacitance ratio of similar to 10:1 fo r a heterostructure varactor. To realise this, a new InGaAs/AlAs quant um well-barrier scheme has been fabricated in GaAs technology. The cap acitance modulation involves carrier dynamics via the quantum well eig enstates in contrast to the conventional depletion operation mode.
