Abstract
It is proven that in two dimensions a system of electrons embedded in a uniform neutralizing positive background and interacting by a potential given by cannot exhibit long-range crystalline order at any finite temperature. The proof is conditional to the following prescription for taking the thermodynamic limit: The potential is replaced by a screened potential and is set to zero after the thermodynamic limit is taken.
