A recent study published in a peer-reviewed journal reports a tunnel field-effect transistor (TFET) based on a zigzag antimonene nanoribbon (ZSbNR) with a 12 nm channel length. The device was simulated using density functional theory (DFT) to investigate the effects of a drain pocket (DP) on suppressing ambipolar current, a common issue in short-channel TFETs.
The research, conducted by scientists at [university/institution name not specified in source], demonstrates that the hybrid DP structure effectively reduces ambipolar conduction while maintaining high on-current. The ZSbNR material was chosen for its favorable electronic properties, including a direct bandgap and high carrier mobility.
According to the simulation results, the proposed design achieves a significant reduction in ambipolar current compared to conventional TFETs, making it a promising candidate for low-power, high-performance logic applications. The study highlights the potential of 2D materials like antimonene for next-generation nanoelectronics.
As of May 2026, this work represents a step forward in addressing the challenges of short-channel effects in TFETs, though experimental validation has not yet been reported. The findings were published in [journal name not specified] and are available online.
