Extreme Bond Ionicity in Mg─Te Chalcogenides for Ultrathin Low Voltage Selector‐Only Memory beyond the Leakage Scaling Limit

Advanced Materials, EarlyView.
Mg─Te chalcogenides address the leakage scaling trade‐off in ultrathin selector‐only memory. Structural partitioning in multiphase Mg─Te, combined with highly ionic Mg─Te bonding and Hf interfacial engineering, supports reliable 5 nm thickness operation at low write voltage with suppressed leakage current, narrow threshold voltage distributions, 10 ns ...

Polar Wurtzite NbAlN: A Transition‐Metal Nitride Alloy for Polarization‐Engineered GaN Heterostructures

Advanced Materials, EarlyView.
A novel polar wurtzite alloy, NbAlN, is demonstrated as a transition‐metal‐containing polar barrier for GaN heterostructures. Nb atoms form coherent nanoscale enrichment within the wurtzite lattice without disrupting metal polarity. This study demonstrates that transition metals can be integrated into polar nitrides to enable polarization‐related ...

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

Advanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Current estimation circuit for discontinuous conduction mode flyback pulse‐width modulation controller

IET Power Electronics, 2015
Primary‐side controlled flyback converter has been widely used in low‐power and low‐voltage products for its simple structure and low cost. As most applications require constant‐current control, it is important for the integrated circuit to detect and express the output current accurately.

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Novel high voltage gain dc–dc converter with dynamic analysis

IET Power Electronics, 2021
This study proposes a non‐isolated dc–dc converter based on a coupled inductor and switch‐capacitor–boosting techniques. The goal of the proposed topology is to increase the voltage gain with low‐duty cycle, so voltage stresses are decreased across power
