30.1  INTRODUCTION

Graphene is emerging as a wonder material for future radiofrequency electronics and is mechanically compatible with the ubiquitous integration on arbitrary substrates—rigid [1,2], flexible [3], stretchable [4], and transparent [5]. Several studies have been performed demonstrating GHz unity-gain frequency (ft) in graphene transistors [2]; however, there are minimal reports that also achieve GHz maximum ...
