Can Schred treat the wave function penetration in to the oxide?
Closed | Responses: 1
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)). Can...

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