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. Lui
Schred v1: other materials
Closed | Responses: 1
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 for the same inputs?
simulating InAs in Schred V1 vs V2
Open | Responses: 1
In version 2, I tried the following parameters for InAs: L-valley energy offset: 0.73 X-valley energy offset: 1.02 effective masses: m(gamma)=0.023 m(L)=0.29 m(X)=0.64 The C-V curves I …
x5 larger Ctot than Cox in QM schred V2
Hello, 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 tranport …
Boltzmann statistics does not work
I tried baltzmann statistics for QM or SC. Both did not work. Could you please fix it? Thank you
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 quantum mechanical effects …
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 substrate I …
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 Schred_201_Tutorial.pdf …
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. thanks, Huy
Parameters for GaAs
I just wondering the parameters or the refernce for calculation of GaAs in Schred. Including the orientation, degenerate number, effective quantum mass, effective density of state mass, etc. …
How to simulate DGMOS with schred 2.0 tool?
Exactly same subband energies for 2 ladders
I am simulating DG MOSCAP with Metal gates. Doping-7e18 Metal1 and 2 WF - 4.3eV Voltage - 0 to 4 V SiO2 thickness 1 nm (100) crystal Voltage varying on both gates In the plot for subband …
Quantum Capacitance and Exchange Correlation Potential ??
I run a simulation of a p MOS Cap with metal gate. I tried to compare the influence of the exchange corelation potential on the total capacitance. I can observe a significant difference on the …
schred running ok?
The CV for very thin oxide (considering only G vs considering GLX) on GaAs seems to be exactly similar. Which is surprising. can anyone check wheather schred is running properly or not?
The source code of Schred does not consist with the online version?
I have downloaded the source code of Schred and run in command line. However, the result seemed to be totally different with the online simulation. For example, the input file should be in case …
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 atop of a P+ …

Quantum Size Effects and the Need for Schred
In this paper, we provide a historical overview of the observation of quantum effects in both experimental and theoretical nanoscale devices. This overview puts into perspective the need for …
How do you perform a simulation of a MOS capacitor ON SOI using the Schred tool?
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 device structure (in device …
