region is a class of NanoTCAD ViDES devoted to define to which material the points of the grid belong to.
The attribute of the gate class are the following:
- geometry : (string) describe the geometry of the gate. The implemented geometries are:
- “hex”: hexahedron geometry. If “regiongeometry” is equal to “hex”, 6 values have to be passed to the gate class, and in particular, xmin, xmax,ymin,ymax,zmin,zmax, which univocally define the limits of the hexahedron geometry. For example: fiel_oxide(“hex”,-1,1,-2,3,5,10); In this way, the attributes xmin, xmax, ymin, ymax, zmin, zmax, are set to -1,1,-2,3,5,10, respectively.
- eps : (double) define the relative dielectric constant of the material
