Sažetak
The 1D quantum transport simulations based on a single-band effective-mass Hamiltonian are employed to study resonant tunneling diodes (RTDs) based on width engineered silicene nanoribbons (SiNRs). Numerical analysis is used to assess the peak and valley current and voltage, peak-to-valley current ratio (PVCR), mean negative differential conductance (NDC), maximum output power (PMAX) and intrinsic cut-off frequency (fc), for different dimensions of device regions. We find that a typical nanoscale SiNR-based RTD could potentially offer a peak current of ~8 mA/μm2, PVCR of 1.6, NDC of ~30 mS/μm2, PMAX of ~100 μW/μm2, and fc of ~3 THz.
