2D Canonical Approach for Beating the Boltzmann Tyranny Using Memory
Rafael Schio Wengenroth Silva, Soumen Pradhan, Fabian Hartmann +4
The 60 mVdecade subthreshold limit at room temperature, coined as the Boltzmann tyranny, remains a fundamental obstacle to the continued down-scaling of conventional transistors…
A topological field-effect memristor
Manuel Meyer, Selena Barragan, Sergey Krishtopenko +13
Overcoming the limitations of the von Neumann architecture requires new computational paradigms capable of solving complex problems efficiently. Quantum and neuromorphic computing…
Microscopic Modeling of Polarization Dynamics in Leaky Dielectrics: Insights into Ferroelectric-Like Behavior
Igor Ricardo Filgueira e Silva, Ovidiu Lipan, Fabian Hartmann +2
Based on a microscopic model of nonequilibrium carrier generation in a leaky dielectric, we analytically derive hysteresis loops for the dielectric response of non-polar, non-ferro…
Accuracy Bottlenecks in Impedance Spectroscopy due to Transient Effects
Victor Lopez-Richard, Soumen Pradhan, Leonardo K. Castelano +4
Impedance spectroscopy is vital for material characterization and assessing electrochemical device performance. It provides real-time analysis of dynamic processes such as electrod…
Beyond equivalent circuit representations in nonlinear systems with inherent memory
V. Lopez-Richard, S. Pradhan, R. S. Wengenroth Silva +4
Basic multimode impedance analysis grounded in the availability of nonequilibrium charge carriers and their retarded path towards equilibrium is used to access the inadequacy of eq…
