Was anyone else off-put by the title and this introductory sentence? "The discovery? The creation of two-dimensional materials no thicker than a few atoms — something that's never been seen before in nature."
Two-dimensional space: Length * Width
Three-dimensional space: Length * Width * Height
If the material has thickness, as this material does (even if it is microscopic), it has a non-zero value for the height, ergo it's a three-dimensional object.
