Silvaco problem,define material in Silvaco

[mojtaba1832]

Hi
I am working with Silvaco to simulate one kind of FET transistor.I have some materials with some parameters,I can define these material in Matlab but I cant found these in Silvaco's materials,how can I connect Matlab to TCAD or how can I define material in Silvaco with all of parameters?I want know how do you define material in Silvaco?I want to define new material in this software?

Using atlas in silvaco you can define new material with changing parameters of pre materials
firstly define region with any other example like polysilicon then
material material=polysilicon eg300= permittivity= nc300= nv300= alattice= affinity= etc..


or else
like following


go atlas
mesh
.
.
.
region num=1 x.min=1 user.material=my_oxynitirde x.max=2 y.min=0 y.max=2
electrode ...
doping ...


material material=my_oxynitride user.default=oxide permittivity=9 user.group=insulator
.
.
.


Here my_oxide nitride is user defined material
