Article 5 – Size Effect of Negative Capacitance State and Subthreshold Swing in Van der Waals Ferrielectric Field-Effect Transistors
Abstract: Analytical calculations corroborated by the finite element modelling show that thin films of Van der Waals ferrielectrics covered by a 2D-semiconductor are promising candidates for the controllable reduction of the dielectric layer capacitance due to the negative capacitance (NC) effect emerging in the ferrielectric film. The NC state is conditioned by energy-degenerated poly-domain states […]
Article 4 – Ferri-ionic Coupling in CuInP2S6 Nanoflakes: Polarization States and Controllable Negative Capacitance
Abstract: We consider nanoflakes of van der Waals ferrielectric CuInP2S6 covered by an ionic surface charge and reveal the appearance of polar states with relatively high polarization ~5 microC/cm2 and stored free charge ~10 microC/cm, which can mimic „mid-gap” states associated with a surface field-induced transfer of Cu and/or In ions in the van der Waals gap. […]
Article 3 – Strain-polarization coupling in the low-dimensional Van der Waals Ferrielectrics
Abstract: Using the Landau-Ginzburg-Devonshire phenomenological approach we explore the strain-polarization coupling in the low-dimensional van der Waals ferrielectrics. We evolve the analytical model of the piezoelectric susceptibility of the material in response to the periodic strain modulation, such as caused by a surface acoustic wave. Numerical calculations are performed for recently discovered and poorly studied […]
