Abstract

A material includes a transparent substrate coated with a stack of thin layers acting on infrared radiation including at least one functional layer. The stack includes a carbon-based upper protective layer within which the carbon atoms are essentially in an sp2 hybridization state and the upper protective layer is deposited above at least a part of the functional layer and exhibits a thickness of less than 1 nm.
