“…The structure is honeycomb-like and this suggests that the array of pits may be used as growth template. These results have triggered a number of follow-up studies and similar results where obtained for boron nitride on Ru(0001) [103], Pt(1 1 1) [101,104,105], Cu(1 1 1) [106], Pd(1 1 1) [101,107], and Pd(1 1 0) [108] as well as Ni(1 1 0) [109] and Ni(100) [110].…”

Producing nanoscale structures on solid surfaces in a controlled way is a technologicalchallenge that has an important impact on a variety of fields such as microelectronics, magnetic storagetechnology, and heterogeneous catalysis. Currently most processes are based on a top-down approach,which relies on an active patterning of a surface by, for example, lithography or imprinting. As thedesired structures become smaller these top-down processes will reach the physical limit of their resolution.A bottom-up approach, which is based on a template-controlled growth of nanostructures on a prestructuredsubstrate, can provide access to structural dimensions of only a few nanometers. The challenge forthe growth of such nanostructures on surfaces is to identify and design suitable surfaces, which act astemplates due to their intrinsic physical and chemical properties. These 2-dimensional (2D) templates canthen be utilized to produce nanostructures of metals, semiconductors, or organic compounds.

“…Similarly, Ni(110), Ru(0001) and Rh (111) substrates were also used as the substrates to heteroepitaxially grow h-BN layers. 28,29 However, it was difficult to separate such epitaxial h-BN films from the original substrates without consuming them; therefore, their further characterization and potential applications were limited. In this work, h-BN layers were separated using an electrochemical delamination technique, and the Ni(111) substrates were reusable.…”

We report the growth and transfer of centimeter-sized, epitaxial hexagonal boron nitride (h-BN) few-layer films using Ni(111) single-crystal substrates. The h-BN films were heteroepitaxially grown on 10 × 10 mm 2 or 20 × 20 mm 2 Ni(111) substrates using atmospheric pressure chemical vapor deposition with a single ammonia-borane precursor. The grown films were transferred to arbitrary substrates via an electrochemical delamination technique, and the remaining Ni(111) substrates were repeatedly re-used. A careful analysis of the growth parameters revealed that the crystallinity and area coverage of the h-BN films were mostly sensitive to the sublimation temperature of the ammonia-borane source. Moreover, various physical characterizations confirmed that the grown films exhibited the typical characteristics of hexagonal boron nitride layers over the entire area. Furthermore, the heteroepitaxial relationship between h-BN and Ni(111) and the overall crystallinity of the film were thoroughly investigated using a synchrotron radiation X-ray diffraction analysis including θ-2θ scans, grazing incident diffraction, and reciprocal space mapping. The crystallinity at the microscopic scale was further investigated using transmission electron microscopy (TEM)-based techniques, including selective area electron diffraction pattern mapping, electron back-scattered diffraction, and high-resolution TEM.

“…It is used in several applications, for example, as a protective layer on surfaces [1][2][3][4][5][6][7], as a substrate [8][9][10][11][12][13][14], as an additive in engine oils and plastics [15][16][17][18], and as a solid lubricant [19]. Various surfaces can be coated by h-BN [1][2][3][4][5][6][7][8], including Cu [1,2,8], Rh [4], Ni [6], and Pd [5,7]. Low friction properties are achieved with thin film coatings [1,2,8].…”

Friction between ice-Ih and hexagonal boron nitride (h-BN) has been determined by periodic ab initio calculations. Surfaces of ice-Ih and h-BN were brought into sliding contact, and the interaction energies were calculated as a function of interplanar distance and lateral displacement of the surfaces. The friction between the surfaces was calculated from the interaction energies, producing a friction coefficient of 0.140. Friction is further influenced at high loads by a tribochemical reaction between ice-Ih and h-BN.
