Adv Mater. 2022 Dec;34(48):e2108473. doi: 10.1002/adma.202108473. Epub 2022 Mar 9.


Over the past two decades, research on 2D materials has received much interest. Graphene is the most promising candidate regarding high-frequency applications thus far due to is high carrier mobility. Here, the research about the employment of graphene in micro- and millimeter-wave circuits is reviewed. The review starts with the different methodologies to grow and transfer graphene, before discussing the way graphene-based field-effect-transistors (GFETs) and diodes are built. A review on different approaches for realizing these devices is provided before discussing the employment of both GFETs and graphene diodes in different micro- and millimeter-wave circuits, showing the possibilities but also the limitations of this 2D material for high-frequency applications.

Keywords: 2D materials; amplifiers; diodes; field-effect transistors; frequency multipliers; graphene; monolithic microwave integrated circuits.
