SEMI: How does ALD compare with other coating methods such as anodization and plasma spray? Sneck: ALD enables conformal dense and pinhole-free coatings on complex shapes. We can deposit various ALD ...

One of the unexplored frontiers in ALD is the enhancement of ALD reactions using non-thermal methods. We are exploring the ability of low energy electrons to enhance ALD reactions. The goal is to ...

Platinum (Pt) doping using ALD method is also performed, in order to improve treatment efficiency, and it has been demonstrated to be very useful for increasing TiO2 photoactivity. The ALD process and ...

in a process known as the atomic layer deposition (ALD) method. The ALD created an oxygen-deficient tin oxide layer, which reduced the band offset to a thicker, overgrown layer of normal tin oxide.

Plasma ALD methods depend heavily on ions. Ions can enhance the quality of films, especially when used with nitrides and at lower deposition temperatures. But some substrates and interfaces could be ...

ALD is a highly precise and controlled deposition method that involves the sequential introduction of gaseous precursors to a substrate, resulting in the layer-by-layer growth of ultra-thin films. ALD ...

Astrophysics observations at ultraviolet (UV) wavelengths often probe the most dynamic aspects of the universe. However, the high energy ...

Our main research topic is thin films and Atomic Layer Deposition (ALD) but also other methods for thin film deposition and nanostructure preparation are studied. Helsinki Ac­cel­er­ator Laboratory ...
