'Nano-Piezotronics' -- New Class of Electronic Components

This diagram compares a nanowire/nanobelt based field effect transistor (FET) with a piezoelectric FET. The role played by a gate electrode is replaced by the piezoelectric field produced across the nanowire/nanobelt by an external force (F) so the transport current is gated by the degree of nanowire bending.
