The invention relates to a method for manufacture of an electrical contact on a structure (10) made of an anisotropic material NA which exhibits an anisotropic electrical conductivity, where the structure (10) exhibits an axial electrical conductivity along a first axis XX′ of the structure (10) and an orthogonal conductivity along a direction YY′ orthogonal to the first axis XX′ of the structure (10), where the orthogonal conductivity is less than the axial conductivity, where the method comprises: a step for the formation of a conductive electrode (20), with an initial thickness Ei, comprising a species M, on a first surface (30) of the structure (10), where the first surface (30) is orthogonal to the orthogonal direction YY′; the method being characterized in that the step for the formation of the conductive electrode (20) is followed by a step for implantation of species X through the conductive electrode (20), into the structure (10).
