In this paper, we propose an analytical drain-current model for long-channel junctionless (JL) cylindrical surrounding-gate MOSFET (SRG MOSFET). It is based on surface-potential solutions obtained from Poisson’s equation using some approximations and separate conditions. Furthermore, analytical compact expressions of the drain-current have been derived for deep depletion, partial depletion, and accumulation mode. The confrontation of the model with TCAD simulation results, performed with Silvaco Software, proves the validity and the accuracy of the developed model

In this paper, we propose the analytical modeling for fully depleted surrounding gate TFET surrounding gate tunneling field effect transistor with single metal gate. This model comprises the surface potential using 2-D Poisson’s equation and drain current with the effects of oxide thickness, silicon thickness as radius, drain voltage, gate metal work function, and assuming channel is fully depleted. The model is tested using TCAD Simulation Tool.
