thermodynamics - Why a mono-atomic crystal layer (2D) can't be stable?


According to Peierls and Landau, 2D crystals were thermodynamically unstable. They can't exist! Of course, this theory was disapproved in 2004 (example: graphene).


What is the general definition of stability of a general system?


What is the thermodynamics' stability?
