Three‐dimensional Antimony Sulfide Based Flat Optics

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Exciton Binding Energy Modulation in 2D Perovskites: A Phenomenological Keldysh Framework

open access: yesAdvanced Functional Materials, EarlyView.
The intrinsic screening effects are successfully decoupled from structural distortion by rigorously designing a series of 2D perovskites. This enabled us to demonstrate how the dielectric environment modulates the quasiparticle bandgap and exciton binding energy.

Artificial neural network-enhanced unconditionally stable finite-difference time-domain technique for multiscale problems

open access: yesScientific African
Electromagnetic sensing and system-level design challenges are often multiscale in nature, making them difficult to solve. These challenges will likely continue to hinder system-level sensing and design optimization for the foreseeable future. Typically,

Selective Charge Injection via Topological van der Waals Contacts for Barrier‐Free p‐Type TMD Transistors

open access: yesAdvanced Functional Materials, EarlyView.
 Topological van der Waals contacts represent a new class of electrodes for 2D semiconductors, enabling precise control of the Schottky barrier height (SBH) and contact resistance (RC) through interlayer distance and orbital hybridization engineering. In Se‐based transition metal dichalcogenides, these contacts achieve an ultralow SBH of 7 meV, RC of 0.

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response

open access: yesAdvanced Functional Materials, EarlyView.
This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

open access: yesAdvanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...
