Phase-Topology Classification of Memristor Hysteresis Loops via Self-Crossings
Ovidiu-Zeno Lipan, Eric Neuhaus, Rafael Schio Wengenroth Silva +6
Memristive devices have revolutionized non-volatile memory and neuromorphic computing, yet the geometry of their hysteresis loops -- in particular, the occurrence and robustness of…
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…
Gate-controlled analog memcapacitance in LaAlO3/SrTiO3 interface-based devices
Soumen Pradhan, Victor Lopez-Richard, Igor Ricardo Filgueira e Silva +8
Current memcapacitor implementations typically demand complex fabrication processes or depend on organic materials exhibiting poor environmental stability and reproducibility. Here…
