Hello,
I am new to Sentaurus TCAD and am facing a problem regarding defining mole fraction in SDE. I have a few questions regarding the mole fraction definition in the channel of my SiGe MOSFET.
1. Should I define mole fraction in SDE using the following commands wherever appropriate?
(define x_SiGe 0.5)
(sdedr:define-constant-profile "CP.xMole" "xMoleFraction" x_SiGe)
(sdedr:define-constant-profile-material "CP.xMole" "CP.xMole" "SiGe" 0 "Replace")
2. Or is it sufficient to define the mole fraction only in the Physics (Material) section of the file in SDEVICE?
My device has successfully run for both the methods with a slight change in on current and zero change in off current.
3. Does it mean that I can use any one of the program of SDE?
Thank you.
