gapmaterial
Gapmaterial is a term used in materials science and device physics to denote a class of materials that are engineered to possess a tunable energy or optical gap. The exact definition varies by author, and gapmaterial is not a standardized category; in many discussions it refers to materials whose band gap can be adjusted through composition, thickness, strain, or external fields, enabling control over electronic and optical response.
Typical properties include a sizeable and controllable band gap, potential for high carrier mobility, compatibility with
Common approaches to realize gapmaterials include two-dimensional semiconductors with engineered band gaps, layered heterostructures, and organic–inorganic
Synthesis and processing methods often involve chemical vapor deposition, molecular beam epitaxy, or solution-based techniques, with
Applications envisioned for gapmaterials include photovoltaics, photodetectors, light-emitting devices, and quantum technologies, where a tunable gap
