I'm trying to extract LTP and LTD graphs via Sdevice after doing a SPROCESS design for gate-all-around, but I'm struggling with an error that says Newton didn't converge, trying again with smaller timestep.
Some of my solve code is
NewCurrentFile="tmp"
Quasistationary(
InitialStep= 0.0010 Increment= 2 Decrement = 2
MinStep= 1e-5 MaxStep= 1
Goal { Name="drain" Voltage= 0 }
){ Coupled {poisson electron hole eQuantumPotential Contact } }
Transient (
InitialTime=1 FinalTime=2 InitialStep=0.010 MaxStep=0.05 MinStep = 1e-5
Goal{Name="drain" Voltage=3}
)
{ Coupled { poisson electron hole eQuantumPotential Contact }}
Quasistationary(
DoZero
InitialStep= 0.0010 Increment= 2 Decrement = 2
MinStep= 1e-5 MaxStep= 1
Goal { Name="gate" Voltage= 0 }
){ Coupled { poisson electron hole eQuantumPotential Contact } }
NewCurrentFile="V-0"
Transient (
InitialTime=1 FinalTime=2 InitialStep=0.010 MaxStep=0.05 MinStep = 1e-5
Goal{Name="gate" Voltage=-4}
)
{ Coupled { poisson electron hole eQuantumPotential Contact }
Plot(FilePrefix="n@node@_VG_0" Time=(range = (0 1)) )
}
How can i solve this problem??
