Exploiting ambipolarity in graphene field-effect transistors for novel designs on high-frequency analog electronics
Francisco Pasadas, Alberto Medina-Rull, Francisco G. Ruiz +8
Exploiting ambipolar electrical conductivity based on graphene field-effect transistors has raised enormous interest for high-frequency (HF) analog electronics. Controlling the dev…
Graphene on Silicon Hybrid Field-Effect Transistors
Mykola Fomin, Francisco Pasadas, Enrique Marin +9
The combination of graphene with silicon in hybrid devices has attracted attention extensively over the last decade. Most of such devices were proposed for photonics and radiofrequ…
Compact Modeling of pH-Sensitive FETs Based on Two-Dimensional Semiconductors
Tarek El Grour, Francisco Pasadas, Alberto Medina-Rull +7
We present a physics-based circuit-compatible model for pH-sensitive field-effect transistors based on two-dimensional (2D) materials. The electrostatics along the electrolyte-gate…
Unveiling the impact of the bias-dependent charge neutrality point on graphene-based multi-transistor applications
Francisco Pasadas, Alberto Medina-Rull, Pedro Carlos Feijoo +6
The Dirac voltage of a graphene field-effect transistor (GFET) stands for the gate bias that sets the charge neutrality condition in the channel, thus resulting in a minimum conduc…
Multi-scale analysis of radio-frequency performance of 2D-material based field-effect transistors
A. Toral-Lopez, F. Pasadas, E. G. Marin +5
Two-dimensional materials (2DMs) are a promising alternative to complement and upgrade high-frequency electronics. However, in order to boost their adoption, the availability of nu…
A Graphene Field-Effect Transistor Based Analogue Phase Shifter for High-Frequency Applications
A. Medina-Rull, F. Pasadas, E. G. Marin +5
We present a graphene-based phase shifter for radio-frequency (RF) phase-array applications. The core of the designed phase-shifting system consists of a graphene field-effect tran…
