The crystals revealed quite different topographic structures, including step-shaped surfaces, outgrowths from the crystal bulk, fine particles intergrown to the bulk, surface roughness and in case of a type B grade HMX a highly defective surface layer. Stochastic methods were applied to quantify surface parameters such as the density and mean height of outgrowths/particles and the mean depth of the porous surface layer.en660conference paper
