Title: in the latest ATK 12.8,2, the relax problem
Post by: njuxyh on May 3, 2013, 15:07

i just do a test calculation in the new version 12.8.2
i have a question about the relax process.

as i know, in the older 2008 version, along the transport direction, i.e z direction, the device region is not relaxed.

in other word, the distance along z direction between the right and left electrode is fixed.

so i am wondering the new version 12.8.2, the device region can relaxed in the z direction?

Yes, this can be done if you choose to not constrain the strain in the Z direction.
