S Parameter Measurements of Superlattice Heterostructure Barrier Junctions towards THz Varactors

摘要

The development of terahertz devices requires new methods to increase the power efficiency. Despite the technological advancement, new ideas are needed to break the terahertz barrier. In this paper we propose a comparison from the power efficiency point of view between the classical heterostructure barrier varactor and the superlattice barrier varactor. The S parameter measurements revealed that the superlattice HBV has a better power performance than the normal one, due to the improved current blocking.
