Hello guys, I am actually having a pretty bad time with some simulations using Atlas from Silvaco.
My code is very simple, I want to simulate a nanowire transistor but every time that I run the simulation, I can't open the log file that stores the results..
This is my structure :
#Criação da estrutura transistor 3D (Polissilicio em toda região)
mesh cylindrical three.d
# Criação da malha no sentido radial
r.mesh l=0.0 spacing=0.002
r.mesh l=0.01 spacing=0.0001

r.mesh l=0.014 spacing=0.001
# Divisão dos ângulos
a.m l=0 spac=45
a.m l=360 spac=45
# Divisão da malha no eixo Z (3D)
z.mesh l= -0.15 spacing = 0.025
z.mesh l= -0.1 spacing=0.002
z.mesh l= 0 spacing=0.02
z.mesh l= 0.1 spacing=0.002
z.mesh l= 0.15 spacing=0.025

solve vdrain = -0.05
solve vdrain = -0.1
solve vdrain = -0.2
solve vdrain = -0.5
log outf=test1.log
tonyplot test1.log
quit
Does anyone know what can I do ?
Dear Fernanada,
I am not very sure, but please check the command formatting for oxide. I have listed down the syntax for Germanium and Oxide below:
region num=1 material=Germanium a.min=0 a.max=360 z.min=-0.15 z.max=0.15 r.max=0.01
# Definição do óxido de porta
region num=2 material=oxide a.min=0 a.max=360 z.min=-0.15 z.max=0.15 r.min=0.01 r.max=0.014
Please run oxide syntax as "Oxide" instead of "oxide".
Please inform me, whether it worked or not.
Regards
Ajay
I guess, you should state "log outf=test1.log" before the "solve" commands and close log by the " log off " string after.
In your case, you execute "solve"-block, then you start log and write nothing in it.
Oh that makes senses..
I tried it here and you solved my problem ! I just needed to put the statement log before the solve functions.
Thank you very much.
