Fig. 3From: Structure Investigations of Islands with Atomic-Scale Boron–Carbon Bilayers in Heavily Boron-Doped Diamond Single Crystal: Origin of Stepwise Tensile StressX-ray synchrotron diffraction pattern (ID01, ESRF) taken from the middle part of the narrow BDD plate. The most intense reflections correspond to the distances between boron–carbon layers 12.36 and 6.18 Å. Low-intensity reflections originate from islands with other periods (not indexed). In particular, the peak at 2θ = 12.2° can be assigned as fifth order from islands with period equal to ~ 37.08 ÅBack to article page
