The pair function P ( r ) determined from atomic models was analysed for models in the form of small atomic layers made up of six‐membered rings occurring in the amorphous structures of materials with crystalline structure of the hexagonal type. the effect of the properties of a single‐layer model on P ( r ) was determined, including its dimensions and shape, and for models from two layer types the influence of the combination and intermixing of their elements was also investigated. The effect on P ( r ) of the combination of such layers into turbostratic stacks was analysed for the initial stage of formation of such stacks. From the form of P ( r ) one can determine both the dimensions of the layer and the existence of stacks of layers, and also the initial stage of the formation of stacks.
