Analog Signal Summation for Reinforcement Learning via Simultaneous Light–Voltage Modulation in a Synaptic Device

Advanced Science, EarlyView.
To overcome limitations of conventional AI hardware, a light‐voltage dual‐modulating synaptic (LVDS) transistor using an IGZO/InAs quantum dot hybrid structure is proposed. LVDS transistor enables analog summation for Dueling Deep Q‐Networks by independently modulating memory via optical and electrical stimuli.

Al Nanoparticle‐Decorated Metal Oxide Synaptic Transistors for Ultralow‐Energy Neuromorphic Computing with Wide Dynamic Range

Advanced Science, EarlyView.
A nanoparticle‐engineered electrolyte‐gated memtransistor is introduced as a materials‐level strategy to overcome the intrinsic trade‐off between energy consumption and synaptic precision. By embedding aluminum nanoparticles at the oxide–electrolyte interface to modulate ion trapping dynamics, the device achieves stable multistate plasticity under ...

Modular Calabi-Yau fourfolds and connections to M-theory fluxes

Journal of High Energy Physics
In this work, we study the local zeta functions of Calabi-Yau fourfolds. This is done by developing arithmetic deformation techniques to compute the factor of the zeta function that is attributed to the horizontal four-form cohomology.

Three‐Terminal Memristor with Tunable Volatility and Set Voltage

Advanced Electronic Materials, EarlyView.
A reconfigurable three‐terminal memristor with an alloyed Ag–Sn source electrode is presented in this work. This versatile device exhibits multiple resistive switching operation regimes that can be customized by an applied gate voltage. The polarity of the gate voltage determines the volatility of the device, whereas its magnitude modulates the low ...

Persistent Homology Analysis of Graphene Surface Morphology Toward Carrier Mobility Evaluation

Advanced Electronic Materials, EarlyView.
Persistent homology analysis is applied to understand the relationship between graphene surface morphology and carrier mobility. While arithmetic mean roughness fails to capture critical structural variations affecting carrier transport, our analysis leverages topological data from AFM images to uncover meaningful correlations.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

Advanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Trifluoracetic Acid‐Driven (002) Facet Engineering of Zn Metal Powder Anodes for High‐Performance Aqueous Zinc‐Ion Batteries

Advanced Energy Materials, EarlyView.
A selective surface engineering strategy is presented for zinc metal powder (ZnMP) anodes in aqueous zinc‐ion batteries. Trifluoroacetic acid treatment enriches the exposure of (002) planes, forming a stepped hexagonal morphology that suppresses hydrogen evolution and dendrite growth.
