|Researchers at Purdue University have developed a repeatable and controllable method for graphene transfer. Graphene is a material that has extraordinary mechanical, electrical, and thermal properties. It has enabled advancements in nanotechnology. Unfortunately, the development has been slowed due to the inability to transfer graphene in a clean and controllable manner.
Purdue researchers have developed a novel technology that transfers graphene to a flat surface in a repeatable and controllable manner. This method, known as atomic stamp, is able to transfer graphene with a coverage of ~80%. Furthermore, the cleanliness of transfer exceeds other known methods with nearly a two-fold increase. This technology can be utilized to more effectively transfer graphene to further the development of nanotechnology.
Technology Validation: Raman spectroscopy was utilized to quantify the amount of cuprous oxide via the atomic stamp method. The results were utilized to identify the coverage and cleanliness of the transfer method.
