Popis:	The edge-energy of a 2D electron gas with high density is calculated, where the edge-energy implies the energy which is needed to form a unit length of a new edge when a 2D infinite homogeneous electron sheet is cleft into two pieces of semi-infinite sheets. It is found that, when rs < 0.415, the edge-energy becomes negative. It indicates that at high enough density the 2D homogeneous electron gas will be unstable and some kind of CDW appears.
