Glancing Angle Deposition (GLAD) is a technique for fabricating materials with controlled structure. It is based on thin film deposition, by evaporation or sputtering, and employs oblique angle deposition flux and substrate motion to allow nanometer scale control of structure in engineered materials.
The substrate is oriented at a large oblique angle relative to the incident vapour flux (a > 75). This leads to an effect called atomic shadowing and results in a porous structure with isolated columns of material growing toward the vapour source. The substrate is then rotated or tilted during deposition to engineer desired microstructures.
