The resistivity of boron doped polycrystalline diamond films changes with boron content in a very complex way with many unclear factors. From the large number of parameters affecting boron doped polycrystalline diamond film’s conductivity we focused on the role of boron atoms inside diamond...

A numerical method is proposed in order to track field lines of three-dimensional divergence free fields. Field lines are computed by a locally valid Hamiltonian mapping, which is computed using a symplectic scheme. The method is theoretically valid everywhere but at points where the field is...

The orienting action of a mica surface on nematic liquid crystals is studied using a polarizing microscope. The experiments show that anchoring transitions can be induced by mechanical strain of the crystal surface. Characteristics patterns of phase boundaries are observed close to genuine or...
