SCRAMBLE: Sweep Comparison Research Application for Multiple Back-Gated FieLd Effect measurements of graphene field effect transistors

Abstract

Graphene Field Effect Transistors (GFETs) are active electronic components which exploit the modulation of charge carriers in a graphene channel for a wide variety of applications such as electronic switching, amplification and biosensing. Herein describes a new software package SCRAMBLE, written in Python and developed with a graphical user interface, to speed up the routine processing of multiple back-gated electrical measurements from GFETs. For forward and reverse sweeps, SCRAMBLE automatically determines the Dirac points, positions of maximum transconductance and calculates the field effect mobilities for electrons and holes.
