How to change the dopant atoms or Dopant Ionization energy in Silvaco Atlas?

I have been trying to simulate C-V plots in Silvaco Atlas for different dopants. I have specified the dopant as Indium while specifying the doping, and Silvaco is also not giving me any errors....

Is there a method to directly find out the depletion width in a MOSFET/MOSCAP at different gate voltages in Silvaco or Sentaurus TCAD(at low temps)??

I'm trying to model the depletion width of a MOSFET at cryogenic temperatures. I would like to see the depletion width in MOSFETs directly in the TCAD software. Any help would be appreciated.

Does the dopant activation energy of Boron or Phosphorus or any other such dopants vary with temperature or not??

I am working on cryogenic modeling of MOS Transistors and in that case I have to include incomplete ionization. That certainly puts E_A as a very important parameter. So I was just wondering if...

What is the depletion width in a MOSFET at cryogenic temperatures including incomplete ionization?

I'm looking to find out the depletion width in a MOSFET including incomplete ionization. A closed form equation is not necessary. Any numerical method to figure it out using integration would be...

Can someone give me some reference or information about the variation of dopant ionization energy in silicon as a function of temperature?

I recently found out that TCAD(Sentaurus) changes the E_A of Boron as a function of doping. EA=EA0 - (3.1*10-8*NA1/3) The reference given in the Sentaurus Device Manual was P. Y. Yu and M....

Why does the effect of incomplete ionization in Silicon increase with increase in doping concentration?

As we increase the doping concentration in silicon, even at room temperature the dopants are not fully ionized. Mathematically it all makes sense. But what is the physical reason behind this...

I'm looking to find a compact model of the attached image. Can someone help me with the kind of function that would get me this kind of curve?

Hello everyone. I'm trying to model a curve that looks something like the attached file when plotted with a logarithmic x axis. And something like a parabola(not exactly. I tried a parabolic...
