Find the file and either add its directory to the search path (I don't use the silvaco tcad tools, you'd have to read the Help docs and see about that) or give the file name as full-path, like "C:\blah\blah\mos1ex10_1.log"
please share me the source code for finding the dark current for the ZnO/p-Si heterojunction photodiode.
Hi I am new to silvaco. I am trying to play around with built-in examples from Solar file. However, when I run it, there are some windows pop up: permission denied in Tonyplot. How can I fixed this issue. Actually when I installed the software yesterday, there was hardlock.sys file (null) processing error. However, I still installed the software.
You're talking about tcad and you might look at the web pages of companies like silvaco who make those tools, you'll find app notes and papers which should lead you as far as you care to go.
Need help about tcad silvaco ( meshing)
Hello everyone, please can someone explain to me how we mesh in Atlas or DevEdit of tcad-silvaco, For defining mesh in x axis and in y axis, do we use FEM finite element method to make values like the exemple for Atlas: what method do we do to define the loc and spacing , or we define them as we like ? Please I need help. mesh space.

I'm conducting the silvaco Atlas 2D simulator for designing a high-k dielectric double-gate mosfet. For beginning, I found a good example from the internet: The authors have used HfO2 and SiO2 separately in order to compare
I have been using the Gateway / Expert / Guardian / SmartSpice tools, have designed one analog product and some test chips with it. I am using the Windows version because it has better support for most of the point tools (exception being, tcad is better off with Linux version). I used Cadence since they were SDA running on Masscomp 68K statio

Hi everyone, I am new on silvoco tcad,i am designing a device on it of 32nm fgmos but the problem here is "lateral diffusion" and the junction is not finding properly, the command i used for it is implant arsenic dose=1e15 energy=10 pleaase suggest me proper command that i can use to implant n type material by reducing lateral diffusion for 32
I am simulating a circuit using devices designed using silvaco ATLAS in Mixed Mode. Now, there is no convergence error while finding IV Characteristics of the designed device but when I'm using that particular device in a circuit, on simulation is giving me a message in the Command Bar which states Warning: Not A Numbers found in currents.

Hi Does anybody have an idea for 22 nm GaN p-MOSFET simulation in athena silvaco tcad?
Is there any possibility in silvaco tcad to introduce Band gap in material. i want to use different energy band gap for different transport direction of a material. i.e.transverse direction one energy gap value and longitudinal directon different energy value to support all transverse modes of material.
The silvaco tools purport to let you turn a device mesh tcad simulation into a SmartSPICE model. Pick a LEVEL that has good correspondence to one of the Spectre compact models, and use simulator LANG=SPICE to make Spectre digest the syntax in that model file. Many, many examples and such on the silvaco support pages. You may have to create (...)

hi.. i am new to silvaco. I am facing difficulty in plotting the final graph. I am trying to create a simple structure of a varistor which is almost similar to diode where the base is TiO2 and dopants used are SiO2, Bi2O3, Ta2O5 and WO3 which will be varied for different experiments. The size of the varistor is 5mm. I would also like to know how
can anyone help me how to design a 65nm nchannel mosfet using silvaco tcad ??? i dont any method trying a lot but didnot get...
silvaco also has front-back tools (with a nice tcad integration as well) and has been pretty active with university support. But that probably will depend on which university, where.
Hello everyone, I used the silvaco tcad to extract capacitance of the PN junction. first, using the 2D structure, the extracted capacitance with unit F/μm. then, I change to 3D structure, but the result also shows that the unit of capacitance with F/μm. I want to know why there is no difference in unit of capacitance between 2D and

Btw, the stressing test script that i am using is from example from silvaco in below link. The code is stressing from 0.01s to 1000s. Seems like I got the similar trend of shifted Vth. I am not sure whether the code is correct in stressing the device? Does the stressing time of 0.01s valid? I think it is too short in stressing the devic
Hello, I am new to this forum. I have just started learning silvaco tcad software using the examples given in their website. I am interested in simulation of organic LEDs and determining mobility. In the tcad examples (Organic) in ATLAS, I found 3 examples and it said that in the 3rd example : Doping Dependent Hopping Mobility)
The ideal way to learn tcad... First, it is very useful (I would say - it's mandatory) to know (or learn) the device physics of the device that you are planning to simulate. Learn what Ohmic contact is, doping, p-n junction, carrier lifetime, electric field, basic parameters of the semiconductor, potential, the difference between potential and vol
hello there!! I'm trying to design a thermistor using silicon that can measure temperatures like 10k - 100k.. I've got all the structure and everything right, i've used 'Transport Equations' and 'Energy balance transport equations', so they are dependent on the lattice temperature, but i can't find a way to change temperature of the surrounding.
