I need to define my material which is Si and SiC and then run it in different temperature. I put model=a-si for defining Silicon but I do not know how to define SiC. I also need to run my program in different temperature, I mean I am wondering if nanohub will automatically calculate different parameters such as Eg, Nc, Nv, mobility and velocity in different temperatures.

Actually I want to have something like the following code,

mesh nx=1000 xres=1.0 layer tm=0.05 nd=1.0e15 model=a-Si layer tm=0.03 nd=1.0e7 model=SiC

tempk=400

solve itmax=100

i-v vstart=0.0 vstop=4 dv=0.1 output info=5 step=1

and in each run just change temperature and without defining the new parameters (due to changing temperature) be able to get the band diagram in different temperature.
