With the rapid advancement of display and smart lighting technologies, micro-light-emitting diodes (Micro-LEDs) have garnered substantial attention due to their exceptional performance characteristics. However, a significant challenge persists in achieving reliable interconnections between Micro-LED chips and driver backplanes. This article proposes and implements the Double-Layer Photoresist Structure

Due to the relatively small particle size of single crystals, the high specific surface area increases the side reactions between the electrode and the electrolyte. Without proper surface modification, single-crystal particles tend to interact directly with the electrolyte, leading to side reactions that impair the electrochemical performance of the material. To address this issue, constructing a coating

We achieved ultrahigh temperature stability of the piezoelectric coefficient d33 by doping heterovalent ions in the PbZr0.54Ti0.46O3 ceramics at the A/B sites in the ABO3 lattice. The Sm3+-ion amount at the A-site remains constant, while the Ta5+-ion amount at the B-site changes. We utilized electron paramagnetic resonance (EPR) and X-ray photoelectron spectroscopy (XPS) to investigate the reduction

The Mg-2.10Zn-0.58Ca-1.02Zr-10.34SiCp (wt%, SiCp/ZX20K) composites were fabricated by stir casting and hot extruded at 400 °C with extrusion speed of 5 mm/s and 10 mm/s, respectively. The SiC particles, which initially exhibited a necklace-type distribution at the grain boundaries, transformed into a band-type distribution after hot extrusion. The SiCp/ZX20K composites underwent complete recrystallization

High entropy alloys (HEAs) have shown good mechanical, electrical, and magnetic properties; thus, they are considered as next-generation structural–functional integration materials. Recent investigations have reported that the “negative mixing enthalpy solid solution” strategy can improve strength–ductility synergy in HEAs {An et al., Nature, 2024, 625(7996)}. However, its effects on magnetic properties

Characteristics of stacking fault spacing
