We investigate the effect of symmetrical geometrical constrictions on the electrical characteristics of ultrathin silicon-on-insulator nanowires with a trigate structure using a 3-D numerical quantum simulator. Introducing barriers at the source and drain junctions profoundly alter the device physics and a transition from 1-D to 0-D quantum behavior is observed. The constrictions create resonance...
Summary form only given: Low frequency oscillations attributed to reflected electrons bouncing between the electron gun and the interaction space have been observed in many gyrotrons. A nonlinear model is considered which allows one to develop the theory based on PIC simulations and apply it to the analysis of these oscillations. Compared to our previous analytical linear theory, in the present nonlinear...
This work studies the influence of gate misalignment on the electrical properties of MuGFETs using both measurements and 3D simulations. Electrical characteristics such as a DIBL, Vth and drain breakdown voltage are shown to be dependent on the gate misalignment due to the resulting change in fin width. Devices that have a Widening of the fin at the Drain side (DW) decreased due to weakening of gate...
