From: New crystal structure prediction of fully hydrogenated borophene by first principles calculations
2D charge density contour of two typical planes in C- and W-borophane. Plane1 is perpendicular to z coordinate axis and contains a B-B bond. Three nearest neighboring B atoms that constitute a triangle determine plane2. The red area represents the electron is dense in the area, however, the blue area represents the electron is sparse in the area.
