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…
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…
Frequency as a Clock: Synchronization and Intrinsic Recovery in Graphene Transistor Dynamics
Victor Lopez-Richard, Igor Ricardo Filgueira e Silva, Gabriel L. Rodrigues +4
Hysteresis and memory effects in graphene field-effect transistors (GFETs) offer unique opportunities for neuromorphic computing, sensing, and memory applications, yet their physic…
Oxide Interface-Based Polymorphic Electronic Devices for Neuromorphic Computing
Soumen Pradhan, Kirill Miller, Fabian Hartmann +9
Aside from recent advances in artificial intelligence (AI) models, specialized AI hardware is crucial to address large volumes of unstructured and dynamic data. Hardware-based AI,…
Graphene Heterostructure-Based Non-Volatile Memory Devices with Top Floating Gate Programming
Gabriel L. Rodrigues, Ana B. Yoshida, Guilherme S. Selmi +7
We present a graphene-based memory platform built on dual-gated field-effect transistors (GFETs). By integrating a lithographically defined metal patch directly atop the hexagonal…
