A barrier layer capable of preventing permeability of moisture, oxygen, other gases, solvents and volatile organic compounds is provided. The barrier layer includes a surface profile undulating in all directions. Further, the surface profile is characterized by the absence of non-undulating surface, straight lines and sharp edges. Further, the surface profile bends in reaction to at least one of thermal stress, mechanical stress, and load caused by deformation of an adjoining substrate or layer. This allows the barrier layer to stretch and shrink in all directions in a plane along the surface profile of the barrier layer and prevents cracking of the barrier layer.
