Title: the gate cover the electrode region?
Post by: njuxyh on February 23, 2019, 05:35

Hi;

i set the dielectric region over the electrode repetition in the scattering region, but you see in the figure following,  above the true electrode, the VNL did not copy the dielectric  region.
so iam wondering how the ATK treat the gate region, in my situation?
the dielectric region has a direct effect on the true electrode  ?

PS： the 2018-6-version, it seems we are allowed to add a gate on true electrode。

You should add spacial (dielectric and/or metallic) regions to the central region before creating Device from Bulk. In this case, the spacial region(s) in the electrode extensions will be extended to the actual semi-infinite electrodes  as well.
