a Circuit symbol, structure and operational principle of the cFET. An air bubble is expanded into the main channel via a trigger channel to control flow resistance in the former. b Symbol and basic operation of an electronic JFET. In this structure, the depletion region reduces the cross-section of the conducting channel, restricting electrical current flow. Despite different physical mediums, the similar geometries of these structures allow for significant theoretical and operational overlap
