Abstract :
Atomistic transport simulation based on non-equilibrium Green´s function and empirical tight-binding methods has been performed for two-dimensional silicon n-i-p devices with a thin strained layer near the source-channel interface. Simulation results show that a compressive strained layer in the source region and a tensile strained layer in the channel region enhance the Zener tunneling current.
