Abstract

We reports observation of giant switching currents in nanopillar transistors at 300 K. It is found that these signals represent mechanical vibration due to the interaction of charging electron and the elastic materials of silicon and silicon nitride. Specifically, when an electron is charged to penetrate the SiN_x/Si/SiN_x multilayer, an electrical force will be initiated to make it vibrate. In addition, such motion will couple to the electronic state in the central Si island for the optimal exchange of elastic and quantum energy. As a consequence, in some mechanical modes, these coupled vibrations will make the transistor functioning like a self-coordinated switching pump for persistent tunnel of electrical current.
