Abstract
The making of carbon films, mainly for use in electron microscopy, by evaporation on to a supercooled organic glass is described. The substrate is dibenzylamine tartrate, with an additive. When molten, standard support grids can be floated on it, so that the substrate is automatically flush with the upper surface of the grids. Large batches of grids can be made in this way without individual handling. Some of the physical properties of evaporated carbon films are discussed.
