The goal of clustering algorithms is to group similar objects together. Figure 2.5.2.125 presents an animation of the density of electrons obtained from 3D simulations at 111 nm under the surface (in the 2DEG region) as a function of the applied bias for gates with more complex geometry (square in Figure 1). return list2DGrid By "infinite" it means it's of size -2147483648 to 2147483647 in both dimensions.
