Materials and Methods The material under study, as noted above, is an axially symmetric nano heterostructure β-CdS/ β-HgS/ β-CdS.
The imposition of a lateral electrostatic field on the β-HgS quantizing layer leads to a narrowing of the band gap of the layer material.

Depending on the material and the geometry being formed, parameters like the infeed, the forming velocity or especially the tool path affect the part’s accuracy.
Because the flank angles is beyond the material specific limit of 65° in some areas the part cannot be formed in one step.
