Numerical Study of Duffing Nonlinearity in the Quantum Dot Embedded Nanomechanical Resonator

Figure 1

Schematics of the quantum dot embedded nanomechanical resonator. The mentioned CNT is clamped doubly between a drain electrode and source which has been suspended just above the given gate electrode; then, the CNT acts as a quantum dot, and single-electron tunneling is the dominant transport mechanism.
