Abstract
Field effect devices having a source controlled via a nanotube switching element. Under one embodiment, a field effect device includes a source region and a drain region of a first semiconductor type and a channel region disposed therebetween of a second semiconductor type. The drain region is connected to a corresponding terminal. A gate structure is disposed over the channel region and connected to a corresponding terminal. A nanotube switching element is responsive to a first control terminal and a second control terminal and is electrically positioned in series between the source region and a terminal corresponding to the source region. The nanotube switching element is electromechanically operable to one of an open and closed state to thereby open or close an electrical communication path between the source region and its corresponding terminal. When the nanotube switching element is in the closed state, the channel conductivity and operation of the device is responsive to electrical stimulus at the terminals corresponding to the source and drain regions and the gate structure.
