semiconductors
what is the real reason ?
the reason of mobility: the spell of goblins who live on the Fermi surface. If you can not believe it, try an obsolete method: reading textbooks.
Now your question makes sense....

sorry i didn't notice that i sent the draft of my question
what is the modeling software for the predictive design of nano-composites materials? i am looking for software can help me to imagine the dispersion nano particles in thermoplastic natural rubber
