Modeling the interface traps-related low frequency noise in triple-gate SOI junctionless nanowire transistors

Abstract

© 2019 Elsevier B.V.The aim of this work is to propose a semi-analytical model for the low frequency noise caused by interface traps in Triple-Gate Junctionless Nanowire Transistors. The proposed model is based on a drain current model, which includes short channel effects influence. The surface potential and the occupied trap density equations are solved self consistently to obtain the traps influence in the static drain current, which is used to determine the trap-related noise. In this work, the low frequency noise of traps in discrete levels is analyzed. The model has been validated with 3D simulations considering different devices characteristics, biases and trap levels. Experimental results have also been used to demonstrate the model suitability.
