The liquid-solid interface in this context, is basically defined as a relatively narrow volume between a crystalline solid substrate (e.g. a crystal) and a fluid (e.g. a droplet of solution providing the molecules to be adsorbed). Experiments prove to be an interesting field to investigate the mechanisms and requirements for interfacial self-assembly of molecules. The mobility of the compound within the fluid and the possibility of incessant exchange of structural molecules with the liquid phase above, result in a wealth of possibilities for structure formation, reorganization, and, in some cases subsequent degeneration. Unlike ultra high vacuum (UHV) conditions, this highly dynamic environment gives room for multiple ways controlling the structure formation, through adapting external parameters.
