Currently i work on Silvaco TCAD Victory Device to simulate a GFET structure. However i face difficulity when defining the material of electrode. I would like to use Nickel as material for electrode but it kept showing Aluminum instead

I wrote syntax as below

ELECTRODE NAME=source material=Nickel x.min=0 x.max=1 y.min=-25 y.max=0

ELECTRODE NAME=drain material=Nickel x.min=9 x.max=10 y.min=-25 y.max=0

ELECTRODE NAME=gate material=Nickel x.min=4.5 x.max=5.5 bottom

material material=nickel user.group=conductor user.default=aluminum

CONTACT name=gate workfunction=4.1

CONTACT name=drain workfunction=4.1

CONTACT name=drain workfunction=4.63

when i ran the syntax, the result shown the Electrode material is Aluminum, not Nickel. How to define Nickel as Material for Electrode in SIlvaco TCAD Victory Device?
