  3. 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?

  4. 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 …

  5. x5 larger Ctot than Cox in QM schred V2

    Closed | Responses: 1

    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 …

  7. Including bulk doping when simulating QM accumulation capacitance in Schred V1

    Closed | Responses: 1

    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 …

  8. Schred V2: Simulating n-type substrates and Vfb determination

    Closed | Responses: 1

    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 …

  10. 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

  16. The source code of Schred does not consist with the online version?

    Closed | Responses: 0

    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 …
