Delocalized Charge Transport in Thermoelectric Composites of Semiconducting Carbon Nanotubes Wrapped with a P‐Type Polymer

Advanced Electronic Materials, EarlyView.
Composites made of semiconducting carbon nanotubes and p‐type polymers, when adequately doped with molecular dopants, can exhibit highly delocalized charge carrier transport, showing high thermoelectric performances. The efficient charge delocalization is enabled by the reduced coulombic binding energy at high carrier concentration and the small ...

Evidence for the exponential distribution of income in the USA

, 2000
Using tax and census data, we demonstrate that the distribution of individual income in the USA is exponential. Our calculated Lorenz curve without fitting parameters and Gini coefficient 1/2 agree well with the data.

Neural Information Processing and Time‐Series Prediction with Only Two Dynamical Memristors

Advanced Electronic Materials, EarlyView.
The present study demonstrates how simple circuits with only two memristive devices are utilized to perform high complexity temporal information processing tasks, like neural spike detection in noisy environment, or time‐series prediction. This circuit simplicity is enabled by the dynamical complexity of the memristive devices, i.e.

Tunable Electronic and Optoelectronic Properties of MoS2 Through Molecular Coverage‐Controlled Polyoxometalate Doping

Advanced Electronic Materials, EarlyView.
Molecular charge transfer at the V12‐DyPc/MoS2 interface stabilizes trions, suppressing neutral A‐exciton emission and enabling controlled modulation of the A–‐trion population, bridging excitonic physics with polyoxometalate charge‐transport functionality.

A Comparison of Alternative Functional Forms For Parametric Estimation of the Lorenz Curve [PDF]

Using U.S. income data, we evaluate several functional forms for the Lorenz curve. On the basis of the goodness of fit, estimated income shares and Gini coefficients, the form proposed by Kakwani (1980) is found to be overall superior to the other forms ...

Suppressed Thermal Conductivity in van der Waals Semiconductor SnS2 by Stacking Engineering

Advanced Energy and Sustainability Research, EarlyView.
Achieving low thermal conductivity is crucial for materials used for thermoelectric energy conversion. It is demonstrated that the lattice thermal conductivity of van der Waals semiconductor SnS2 can be significantly reduced by introducing 2H and 4H structures stacked along the c‐axis.

Harnessing Nonidealities in Analog In‐Memory Computing Circuits: A Physical Modeling Approach for Neuromorphic Systems

Advanced Intelligent Systems, EarlyView.
This work harnesses nonidealities in analog in‐memory computing (IMC) by training physical neural networks modeled with ordinary differential equations. A differentiable spike‐time discretization accelerates training by 20× and reduces memory usage by 100×, enabling large IMC‐equivalent models to learn the CIFAR‐10 dataset.
