Pointillism Pointillism Pointillism () is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism. The term "Pointillism" was coined by art critics in the late 1880s to ridicule the works of these artists, and is now used without its earlier mocking connotation. The movement Seurat began with this technique is known as Neo-impressionism. The Divisionists, too, used a similar technique of patterns to form images, though with larger cube-like brushstrokes. The technique relies on the ability of the
Niemeyer–Dolan technique a well-defined geometry. The Niemeyer–Dolan technique is used to create thin-film electronic nanostructures such as quantum dots and tunnel junctions. Niemeyer–Dolan technique The Niemeyer–Dolan technique, also called the Dolan technique or the shadow evaporation technique, is a thin-film lithographic method to create nanometer-sized overlapping structures. This technique uses an evaporation mask that is suspended above the substrate (see figure). The evaporation mask can be formed from two layers of resist. Depending on the evaporation angle, the shadow image of the mask is projected onto different positions on the substrate. By carefully choosing the angle for each material to be deposited,
