Boltzmann statistics does not work
Open | Responses: 2
I tried baltzmann statistics for QM or SC. Both did not work.
Could you please fix it?
Can i use it for graphene FET simulation to calculate potential distribution in one dimension?

Exactly same subband energies for 2 ladders
I am simulating DG MOSCAP with Metal gates.
Metal1 and 2 WF – 4.3eV
Voltage – 0 to 4 V
How do you perform a simulation of a MOS capacitor ON SOI using the Schred tool?
Open | Responses: 1
How do you perform a simulation of a MOS capacitor ON SOI using the Schred tool? The manual says it’s possible but I find when I click “launch tool”, the only options for...
How to find Vox = f(Vg)
Closed | Responses: 0
I used this SHRED before to generate Vox=f(Vg)of a MOS, as Vg is swept from -V to +V, but am struggling to find the way of how to do it with this new interface.
How to simulate DGMOS with schred 2.0 tool?
I am confused regarding the Material Parameter Inputs. The notation in the input deck is extremely confusing.
The input deck has mx_3valleys (valley 1, valley 2, valley 3), my_3valleys (valley 1, valley 2, valley 3), mz_3valleys (valley 1, valley 2, valley 3), mhh_3valleys (valley 1, valley 2, valley...
Including bulk doping when simulating QM accumulation capacitance in Schred V1
Through examination of the source code I have figured out that I need to use the “accumula=yes” flag in the “calc” section of the input file to get Schred V1 to include...
Input file syntax for Schred V2
I have downloaded and compiled the source code for versions 1 and 2 of Schred. However, I am having trouble finding information on the input file syntax for version 2. The...
Parameters for GaAs
Closed | Responses: 2
I just wondering the parameters or the refernce for calculation of GaAs in Schred.
Including the orientation,...
I would appreciate if somebody gives me instruction for SCHRED compilation in windows.
I also have an ORACLE Virtualbox and I could compile it there, if I knew how.
Thanks in advance.
Schred for non uniform doping?
Is there support for non uniform doping profile for Schred? I’m interested in using inverse modeling of CV to extract the doping profile. I have a situation of a very shallow N+ region...
schred running ok?
The CV for very thin oxide (considering only G vs considering GLX) on GaAs seems to be exactly similar. Which...
Schred v1: other materials
In Schred V1 there is an option for “other” materials. When this is selected I can input effective masses and band offsets.
How is this different from Schred V2, which asks...
Schred V2: Simulating n-type substrates and Vfb determination
Using the compiled Schred V2 code and supplied sample input files I am able to successfully model structures with a uniformly doped p-type Si substrate. I assume that to model an n-type...
schred-1.0 does not account for doping/Temp effects on VFB in DG
I do not noticeable changes when using intrinsic 1E10cm-3 or heavily doped 1E18cm-3 in simulation of metal-DG structures. The same happens when changing temprerature
I would excpect...
simulating InAs in Schred V1 vs V2
In version 2, I tried the following parameters for InAs:
L-valley energy offset: 0.73
x5 larger Ctot than Cox in QM schred V2
I found that the QM with Fermi-statistics in Schred V2 gives five times larger Ctot than Cox when I have tox=0.73 nm and NA=7e18 (and other parameters as defaults except I changed...

Can Schred treat the wave function penetration in to the oxide?
In case of ultra-scaled device, the impact of wave function penetrateion on the invertion charge and Vt is increasing (Ref M. Kauser, et.al., in IEEE TED 49, 693 (2002))....
