Abstract
A field effect transistor construction includes a semiconductive channel core. A source/drain region is at opposite ends of the channel core. A gate is proximate a periphery of the channel core. A gate insulator is between the gate and the channel core. The gate insulator has local regions radially there-through that have different capacitance at different circumferential locations relative to the channel core periphery. Additional constructions, and methods, are disclosed.
