Electrical Anisotropy of Laser-Graphitized Diamond Surface

Abstract On the surface of diamond plate with (100) and (110) orientations the graphitized structures are created by excimer KrF laser irradiation (λ = 248 nm, τ = 20 ns). The electrical resistance of graphitized layers is measured in different directions. Anisotropy of electrical properties is discovered and studied. The obtained results open new possibilities for using laser methods to modify diamond materials and can be used to improve the conductivity of structures in new diamond-based photonic and electronic elements.
