for strained Germanium some Material parameters ( Band Gap, Effective mass and electron mobility) are to be changed accordingly than parameter of normal unstrained Germanium.
Dear Md Erfan, now a days I am using silvaco. But using variables like material= Silicon, eg300=1.12 .... ect are basic commands. How ever I hope if you go through user manual Synopsis Sentaurus, then you will be capable to solve problem.
Good Luck.
Dear Rahi, thank you for your kind feedback. I think your information would help me more or less. But I need more specified solution. Somebodies told me to create datex.text file to create new material file then to paste on directory. But I do not even know what is this datex.text file and how to make it in terms of material parameter. If you know it please give hints...:)
Hi,
you just have to create a text-file datexcodes.txt in your project folder. Then, fill the file with the following pattern:
DATEX2.1
Datacode
"$DateTime: 2012/11/26 18:27:10 $"
"Data codes for semiconductor process and device simulation"
Materials {
Anyinsulator {
label = "Anyinsulator" ! Use this if insulator is unknown.
group = Insulator
color = #ffffa4, #8cff19
alter1 = Insul
}
Anysemiconductor {
label = "Anysemiconductor" ! Use this if semiconductor is unknown.
group = Semiconductor
color = #ffd9e9, #d982c3
alter1 = Semi
}
Copper {
label = "Copper"
group = Conductor
color = #ff7f50, #11b3b3
alter2 = 75
}
AlAs {
label = "AlAs"
group = Semiconductor
color = #0f5ea8, #ff1919
}
}
Just add your own material or modify the present ones. For physical properties, you have to set parameters within Sprocess and Sdevice.
Regards and good luck
Dear Julien Delalleau,
as you said i have made one new datex.text file by copying it from default directory and kept it in my proejct folder. Then I deleted all text inside of it. After that i copied all the code you wrote me in your last comment. And i run the sdevice then it shows error given below:
Could you please tell me what would be solution.
Error in line 1 in file datexcodes.txt:
syntax error
1 errors detected while reading DATEX files.
DATEX not initialized !
terminate called after throwing an instance of 'tbb::movable_exception'
what(): tbb::movable_exception\
Hi,
I also get similiar problem, did you already get the answer of your problem? Thank you so much
In fact, you must keep the existing text in the datexcodes.txt, and then adding following a template. (its better to avoid syntax error)
Please refer to "Utilities User Guide" from Synopsys", Chapter 1:The datexcodes.txt File"
