Filamentary Transport and Thermoelectric Effects in Mushroom Phase Change Memory Cells

This study utilizes 2D finite-element electrothermal simulations to demonstrate that thermoelectric effects and filamentary transport in Ge2_2Sb2_2Te5_5 mushroom phase change memory cells significantly reduce Reset energy and power when current flows from the top electrode to the narrow bottom electrode, while also revealing that programming volume is independent of contact dimensions above 10 nm and that larger contacts trade increased variability for improved reliability.

Improved selector behavior in ultrathin chromium-doped V2_2O3_3 films

This study demonstrates that ultrathin (down to 5 nm) chromium-doped V2_2O3_3 films exhibit improved selector properties, such as low leakage current and abrupt transitions, likely due to an interfacial amorphous layer and Ti diffusion from the electrode that homogenizes the behavior of crystalline and amorphous phases.

Electrical Spectroscopy of Intervalley Relaxation in WSe2_2 Transistors

This paper demonstrates that the transconductance of multilayer WSe2_2 field-effect transistors can serve as a direct electrical spectrometer for measuring intervalley relaxation times, offering three distinct signatures—Lorentzian frequency response, two-stage current transients, and sweep-rate-proportional hysteresis—that provide quantitative access to this parameter using standard instrumentation.

Extending Field Limits in Nanoscale Magnetic Imaging with Metamaterial-inspired Magnetic Flux Concentrators

This paper demonstrates that integrating metamaterial-inspired magnetic flux concentrators onto samples enables nanoscale magnetic imaging techniques to overcome instrumental field limits by locally amplifying magnetic fields, thereby allowing the observation of magnetization processes in magnetotactic bacteria and giant magnetofossils at applied fields significantly lower or higher than previously possible.

Ultra-Soft Ferrimagnetism in a High-Entropy Spinel Oxide Driven by Site-Selective Cation Disorder

This study reports a new high-entropy spinel oxide featuring ultra-soft ferrimagnetism with an exceptionally low coercivity of 1.8 Oe and high electrical resistivity at room temperature, driven by site-selective cation disorder that enables its potential for low-loss, high-frequency applications.

Layer-parity-dependent interfacial coupling in Nb3_3Cl8_8/graphene van der Waals heterostructures

This study demonstrates that the layer-parity-dependent out-of-plane polarization in Nb3_3Cl8_8 governs interfacial coupling with monolayer graphene, resulting in distinct charge transfer, carrier densities, and hybridization gaps that are validated by both experimental transport measurements and density functional theory calculations.

Efficient analytic continuation approach to Bethe-Salpeter excitation spectra in selected energy windows

This paper proposes an efficient analytic continuation method that constructs Bethe-Salpeter absorption spectra within specific energy windows by iteratively calculating polarizability tensors at a coarse set of complex frequencies to form a matrix-valued continued-fraction representation, which is then validated across diverse molecular and nanoscale systems.
