Layer-by-layer (LbL) deposition is a thin film fabrication technique. The films are formed by depositing alternating layers of complementary materials with wash steps in between. This can be accomplished by using various techniques such as immersion, spin, spray, electromagnetism, or fluidics. [1]
It is considered an ideal growth model, requiring perfect lattice matching between the substrate and the layer growing on to it, and it is usually limited to homoepitaxy. [1] For FM growth to occur, the atoms that are to be deposited should be more attracted to the substrate than to each other, which is in contrast to the layer-plus-island ...
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
This layer-by-layer growth is two-dimensional, indicating that complete films form prior to growth of subsequent layers. [2] [3] Stranski–Krastanov growth is an intermediary process characterized by both 2D layer and 3D island growth. Transition from the layer-by-layer to island-based growth occurs at a critical layer thickness which is ...
Gero Decher is a German chemist and Distinguished Professor ("Professeur classe exceptionnelle") at the Faculty of Chemistry of University of Strasbourg.He is best known for his seminal role in the development of polyelectrolyte multilayers, which is today known as “layer-by-layer (LbL) assembly”, [4] a simple yet powerful nanofabrication method that has enabled the development of entirely ...
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and ...
