Aiming at performance enhancements and robust reliability design of mono-layer transition-metal dichalcogenide (TMD) tunneling FET(TFET), W vacancy(Vw) defect is systematically studied in this work. Impacts of Vw defect's positions are characterized in WSe2 TTETs by using rigorous ab initio simulations. It is found that Vw defect that locates in the tunnel junction will increase Ion, while it has...
A novel physical unclonable function (PUF) that based on random telegraph signal noise (RTN) is proposed and studied in this work. Firstly, systematical experiments have been done in ultra-scaled devices with various gate stack structures. It is found for the first time that strong correlations between trap time constants and thermal activation energies universally exist in all devices, no matter...
Active queue management (AQM) mechanism is a powerful method, which aims to assist the TCP congestion control and to improve the trade-off between queuing delay and link utilization. Traditional price-based AQM algorithms suffer from sluggish response, poor robustness, and lack adequate adaptability against dynamic traffics. To improve AQM performance, this paper introduces artificial intelligence...
Congestion control can be regarded a distributed system, which consists of source algorithm like TCP, and link algorithm, such as active queue management (AQM). Shadow price has been derived from optimization theory to be implemented in routers as the AQM algorithm. In this paper, a control theoretic approach to analysis and design of the price is presented to enhance the AQM performance. We analyze...
