Summary: This study reports a low-cost and scalable fabrication method for transparent electrodes based on sprayed AgNW networks coated with MgO thin films deposited by AP-SALD at mild deposition temperature (<= 220 degrees C). The study also presents the first reported method for fabricating MgO thin films by AP-SALD and optimization of their deposition on different substrates. The resulting nanocomposites exhibit high stability under thermal and electrical stress while maintaining approximately 85% optical transparency, thanks to the conformal coating of MgO on AgNW.

Summary: The typical polyol-based synthesis of silver nanowires using insulating polymer as a surfactant limits direct contact between each nanowire, affecting optoelectronic properties. A simple solvent treatment effectively removes the insulating polymer, leading to decreased sheet resistance and increased transmittance. Transparent film heaters using the treated silver nanowire network rapidly reached 150 degrees C under a bias of 5 V, demonstrating great potential for flexible transparent electrode and film heater applications.

Summary: Template-patterned, flexible transparent electrodes (TEs) were formed using an ultrathin silver film on top of the commercial optical adhesive Norland Optical Adhesive 63 (NOA63). The NOA63 base-layer prevents coalescence of silver atoms, creating ultrasmooth continuous films. The combination of 12 nm silver films on NOA63 shows high visible-light transparency and low sheet-resistance, making them ideal for flexible TEs. Etching the NOA63 base-layer before silver deposition allows for the creation of insulating regions, resulting in a patterned TE for flexible devices.

Summary: Micro resistance bonding is a crucial method in the manufacturing of ever-miniaturized electronic components, but the bonding quality is often unstable due to limited understanding of interfacial phases. This study investigated the nano-scale interfacial details of micro resistance bonding Al wire to an Au/Cu pad using transmission electron microscopy (TEM). The research found that metallurgical bonding joints were formed in the Al-Au-Cu system with sufficient interfacial reactions, resulting in the formation of various phases due to the rapid temperature rise and ultrafast cooling speed during the bonding process.
