Study and development of flexible electronic nanodevices for biosensing applications

Abstract

This Thesis aims to develop a comprehensive set of numerical tools specifically designed to analyse 2D materials (2DMs) based Field-Effect Transistorbased Biosensor (BioFET)s. These tools are intended to provide a deeper understanding of their operation principles and to shed light in the fundamental physical and electrical magnitudes involved in their optimization. To that end, a self-consistent numerical platform has been implemented able to solve the set of coupled equations that describes the structure, comprising the FET device and the electrolyte solution containing the biological sample. In summary, the work collected in this Thesis encompasses a flexible and powerful numerical simulator able to describe with great detail the particular features of BioFET devices. The platform is validated against experimental FET and BioFET devices, reproducing them excellently, and it is latter exploited in several studies that yield relevant for the modelling of 2DM-based FET and BioFET devices and their optimization
