kolayers

Kolayers is a general term used to describe layered structures in which successive layers perform distinct functions and interact through defined interfaces. The concept emphasizes modularity, clear separation of concerns, and controlled inter-layer communication within a stack. Kolayers can describe both physical stacks of materials and abstract software architectures, with the specific meaning depending on the discipline.

In software engineering, kolayers denote a modular multi-layer architecture where each layer exposes a stable interface and depends only on the layer directly below it. Typical kolayer configurations separate concerns such as presentation, business logic, and data access. This arrangement enables independent development, testing, and deployment of layers, simplifies maintenance, and facilitates protocol changes at a single boundary while preserving overall system behavior.

In materials science, kolayers describe vertically stacked, two-dimensional sheets held together by weak interlayer forces. The order, composition, and thickness of layers—such as graphene-like materials or transition metal dichalcogenides—control properties including conductivity, flexibility, and optical response. Kolayer stacks are studied for heterostructure devices and sensors, where interlayer coupling leads to novel phenomena not present in single-layer films.

The term appears in interdisciplinary discussions spanning the 2000s and 2010s, drawing on general “layer” terminology and adding a prefix to signal cooperative structure. It remains informal in some fields but is used by researchers to describe architecture and fabrication approaches, emphasizing the shared idea of well-ordered, interacting layers across contexts.
