High-Tech Solutions for Your Research Needs

Nano-layers of metals, semiconducting and dielectric materials are crucial components of modern electronic devices, high-efficiency solar panels, memory systems, computer chips and a broad variety of high-performance tools.

The technique of choice for depositing nano-films on various surfaces is Atomic Layer Deposition (ALD), which uses consecutive chemical reactions on a material’s surface to create nanostructures with predetermined thickness and chemical composition (Figure 1).
