Microtopography‐Guided Radial Gradient Circle Array Film with Nanoscale Resolution

摘要: Distribution of multimaterials at arbitrary positions with nanoscale resolution and over a large area substrate is essential to future advances in functional graded materials. Such stringent requirements are highly beyond the reach current techniques, although newly developed 3D printing technologies addressed. Here, radial gradient circle array film distribution accuracy up ≈18 nm fabricated by using microtopographic substrate. A mathematical model guide position, size, shape, type materials on an section for given morphology The periodic electrical mechanical properties identified, which can be beneficial further functionalization applications, such as refractive index lenses, microcoils, microantennas.
