Grolltex is one of the world’s leading manufacturers of few- and single-layer hexagonal boron nitride (hBN); specializing in a proprietary chemical vapor deposition (CVD) process for extremely pure single-layer hBN at competitive prices. We can generate monolayer materials and heterostructures on a choice of substrates, including copper sheets of 3” x 3” (76mm x 76mm) or 6” x 6” (150mm x 150mm).
Our copper sheets are sourced exclusively from trusted American suppliers, and all growth processes are conducted in a Class 1000 cleanroom environment. We guarantee at least 100% coverage of copper foils with sporadic adlayers and grain sizes of >4μm. Grolltex single-layer hBN sheets on copper are hermetically sealed and are supplied with full Raman measurement data files, for complete peace of mind.
At Grolltex, we can also transfer monolayer hBN onto large-area wafers (4”, 6” or 8” diameters) without stitching. Contact a member of the Grolltext team today if you would like to learn more about our single-layer hBN capabilities.
