Revisiting the Mechanism of Electric Field Sensing in Graphene Devices [PDF]
ACS Omega, 2021 Electric field sensing has various real-life applications, such as early prediction of lightning. In this study, we effectively used graphene as an electric field sensor that can detect both positive and negative electric fields. The response of the sensor is recorded as the change in drain current under the application of an electric field.

Germanium Nanowires as Sensing Devices: Modelization of Electrical Properties [PDF]
Nanomaterials, 2021 In this paper, we model the electrical properties of germanium nanowires with a particular focus on physical mechanisms of electrical molecular sensing. We use the Tibercad software to solve the drift-diffusion equations in 3D and we validate the model against experimental data, considering a p-doped nanowire with surface traps.
