Cleaning graphene: Comparing heat treatments in air and in vacuum

Surface impurities and contamination often seriously degrade the properties of two‐dimensional materials such as graphene. To remove contamination, thermal annealing is commonly used. We present a comparative analysis of annealing treatments in air and in vacuum, both ex situ and “pre situ,” where a...
