bilayeru

Bilayeru is a term used in materials science to describe a family of two-layer heterostructures formed by stacking two monolayers with tunable interlayer coupling. The name combines bilayer concepts with a generic suffix to denote a broad class of materials rather than a single compound.

In bilayeru structures, an inner and outer layer are separated by an adjustable interlayer spacing, often governed by van der Waals forces. The choice of constituent materials, whether inorganic, organic, or hybrid, determines electronic, optical, and mechanical properties through interlayer interactions.

Fabrication approaches include mechanical exfoliation, chemical vapor deposition, and molecular self-assembly, as well as layer-by-layer stacking techniques. Key properties include tunable band gaps, controlled exciton dynamics, and the possibility of twisting or straining layers to create moiré patterns that modify electronic states.

Potential applications span nanoelectronics, optoelectronics, photonics, energy storage, and sensing. Challenges include achieving reliable large-area production, precise control of layer alignment and twist angle, interfacial contamination, and stability under device operating conditions.
