Decoupled graphene thanks to potassium bromide Date: April 29, 2019 Source: University of Basel Summary: The use of potassium bromide in the production of graphene on a copper surface can lead to ...
POTASSIUM bromide has a crystal structure similar to that of rocksalt ; but as the ions in the former are heavier, the Raman frequency shifts are smaller and hence less easy to record in a ...
When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing them ...
