Si(331)-(12x1) is the only confirmed planar silicon surface with a stable reconstruction located between (111) and (110). We have optimized the annealing sequence and are able to obtain almost defect free, atomically precise surface areas approaching micrometer dimensions. The unprecedented perfection of the surface combined with its pronounced structural anisotropy makes it a promising candida...

We prove short-time existence of φ-regular solutions to the planar anisotropic curvature flow, including the crystalline case, with an additional forcing term possibly unbounded and discontinuous in time, such as for instance a white noise. We also prove uniqueness of such solutions when the anisotropy is smooth and elliptic. The main tools are the use of an implicit variational scheme in order...

The theory of simple domain walls in planar nematic films is reconsidered taking into account azimuthal director rotations additionally. A perturbation treatment is useful to derive analytical equations which are asymptotically valid in the limit of small distortion amplitudes. In comparison to previously known approaches a more complete description leads to a correction in the formula for the ...

Recently, hexagonal boron nitride (h-BN) has attracted attention as a high-thermal-conductivity filler for insulating polymers used in electronic devices. However, since the crystal structure of h-BN is analogous to that graphite, exhibits platelet crystalline shape with anisotropy high thermal conductivity in-planar direction and an extremely low trans-planar direction. Consequently, composite...

NiPS${}_{3}$ is a layered van der Waals compound. Like graphite, it can be delaminated down to monolayer. Unlike magnetic. Neutron inelastic scattering has been performed on bulk single-crystal samples of measure the magnetic dynamics, key understanding properties. Clear spin waves are observed, quantifying exchange within and between layers predominantly planar anisotropy. The findings have im...
