Presents the model on the drag resistance to overcome discusses the equations used for calculation of spoked and solid wheel power and force, and gives a table of power output under a certain condition for comparison of two types of wheels, and suggests a scheme to estimate power on a specific track, and the speed and the time spent on a certain track are compared to illustrate the functions of parameters. 展开更多

This paper proposes a laterally graded junctionless transistor taking peak doping concentration near the source and drain region, and a gradual decrease in doping concentration towards the center of the channel to improve the I OFF and I ON/I OFF ratio. The decrease of doping concentration in the lateral direction of the channel region depletes a greater number of charge carriers compared to the uniformly doped channel in the OFF-state,which in turn suppresses the OFF state current flowing through the device without greatly affecting the ON state current. 展开更多
