How to design and simulate a tunnel diode using atlas

Hi all
I am new to silvaco atlas. I was trying to simulate a resonant tunnel diode using atlas but the conduction band energy is coming correct but the plot of IV cure becoming linear. I can't understand the problem. either with the steucture definition or with the model declaration. I have attached the code here. please help me anyway!!!!!!!!!!!!!!!!

go atlas

Hello,

May I know if you had a solution to your problem above?

Thanks.

Hello
I need the code for I-V characteristics of Resonant tunneling Diode.
I really need that please help me..

thanks

hi
i am new in silvaco and excuse me if i speak not good
i want to simulate a mos and want to get energy band for gate and channel
i dont know how
please help me
i need a simulation for mos and then please code for get energy band please
thank you
