There are two basic ideas for making two-dimensional materials: synthesis and stripping, the latter refers to peeling a single layer from a three-dimensional material with a layered structure. Swiss scientists said they used computers to analyze whether compounds could be stripped into single layer, which greatly reduced the workload.　 　　The researchers developed a new algorithm to analyze the structure of more than 100,000 known three-dimensional compounds, initially screened about 5,600 substances with layered structures, and then calculated the energy needed to separate the layers from layers . The results showed that the structure of about 1800 species may be suitable for stripping, in which 1036 species seem to be very easy to strip.
