Molecular collage statics and dynamics


This very technical scientific article can interest, to amuse to see inspiring by the artists collagists.

Molecular collage is a technique of assembly of two materials which know an increasing use in micro-electronics and microtechnology. It is based on the spontaneous adhesion of deix surfaces A and B independently of their respective crystalline structures and when that Ci are sufficiently plane and not very rough. For example it makes it possible to assemble a monocrystal on another, thus creating with L interfaces a macroscopic grain boundary, or it makes it possible to deposit on an amorphous insulator such as silica, a monocrystal of silicon, which makes it possible to manufacture a substrate of the silicon type on insulator (ONESELF). By combining X-radiation and high energy and shaving incidence, we determined the differences in energy of adhesion for different interfaces from joinings. (Hydorphiles, Hydrophobic subjects) according to different the paremeter (Natural of matérieux, roughness, exposure plasma).
