Title: Surface stress on three-terminal vibrational nanomechanical transistor

The impact of the surface effect induced stress on a nanomechanical transistor (NMT) is investigated. It is shown that the surface stress of the doubly clamped beam in the NMT causes an increased resonant frequency, whereas a fluctuated average electrical current. The self-excitation regime of the NMT is studied through bifurcation calculation, which is extended with the surface stress considered.
