Using Dopants as Agents to Probe Key Electronic Properties of Organic Semiconductors

Advanced Electronic Materials, EarlyView.
Dopants are typically used in organic electronics to enhance conductivity, but here their potential is demonstrated as probes for fundamental material properties. By integrating experimental data and multiscale simulations, it is shown how dopant ionization and conductivity measurements enable accurate extraction of ionization potential and Coulomb ...

Toward Reliable Metal Halide Perovskite FETs: From Electronic Structure and Device Physics to Stability and Performance Engineering

Advanced Electronic Materials, EarlyView.
Metal halide perovskite field‐effect transistors (PeFETs) offer great promise for flexible, low‐cost, and high‐performance due to their excellent charge carrier properties. However, challenges like ion migration, hysteresis, and instability limit their performance.

Modeling and Verification of 1/f Noise Mechanisms in FAPbBr3 Single‐Crystal X‐Ray Detectors

Advanced Electronic Materials, EarlyView.
We demonstratethat surface‐trap‐induced carrier number fluctuations are the dominantmechanism in FAPbBr3 Schottky devices, a conclusion supported by thedistinct defect profiles revealed by Drive‐Level Capacitance Profiling (DLCP). Throughnoise contribution decomposition, it is found that the 1/f noise of thedetector is the key noise source affecting ...

Performance Enhancement in Hafnium Oxide Through Homogeneous and Heterogeneous co‐Doping Strategies

Advanced Electronic Materials, EarlyView.
This article presents a comprehensive co‐doping toolkit to optimize the performance and reliability of fluorite‐structure ferroelectrics like hafnium oxide. By employing homogeneous and heterogeneous co‐doping strategies, precise control over crystallization behavior, polarization hysteresis, and oxygen vacancy distribution is achieved.

Synergetic Lattice and Surface Engineering: Stable High‐Voltage Cycle Performance in P3‐Type Layered Manganese Oxide

Advanced Energy Materials, EarlyView.
A dual lattice‐surface strategy employing NaTi2(PO4)3 is adopted to enhance the performance of P3‐type Na0.67[Zn0.3Mn0.7]O2, whereby Ti stabilizes the bulk lattice and surface P species mitigate degradation, collectively improving high‐voltage cycling stability, Na+ diffusion, and oxygen redox reversibility through synergistic structural and ...

Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...
