stacksinterlayers

Stacks interlayers are thin spacer or buffer layers positioned between adjacent stacks in a multilayer assembly. They are used to tailor interfacial properties, control transport of charges or ions, and improve mechanical or thermal stability of the overall structure. The term stacksinterlayers is often employed to describe these interfacial layers in stacked materials, including electronics, energy storage, and protective coatings.

Interlayer materials can be inorganic, organic, or hybrid and may include oxides, nitrides, sulfides, polymers, or two-dimensional materials. Their function depends on the target application: decoupling mechanical strain between stacks, acting as diffusion or chemical barriers, enabling selective charge or ion transfer, or tuning optical and electronic coupling across interfaces.

Synthesis and incorporation methods vary with the chosen materials and platform. Common approaches include mechanical stacking and transfer, chemical vapor deposition, electrodeposition, and layer-by-layer assembly. The interlayer thickness can range from a few angstroms to several nanometers, and surface roughness and chemical compatibility strongly influence performance.

Key properties of stacks interlayers include thickness uniformity, interfacial adhesion, defect density, and chemical stability under operating conditions. The ideal interlayer minimizes unwanted reactions at interfaces while preserving or enhancing desirable interactions between the adjacent stacks.

Applications span energy storage, electronics, and protective coatings. In batteries and supercapacitors, interlayers can improve cycling stability and rate performance by limiting dendrite growth or polysulfide diffusion. In electronic and optoelectronic devices, interlayers can modulate charge injection, trap states, and optical coupling. Ongoing research seeks scalable, defect-free integration and new interlayer chemistries to expand their utility.
