How could change the energy band gap(E-K) using the strain?

  1. Oct 4, 2015 #1
    Hi! i'm sung dae

    with tensile strain, energy band structure could be changed. bang gap decrease
    with compressive strain, energy band structure could be changed. bang gap increase

    but i'm not sure why it could be changed ..

    Is there someone who explain in detail ?

    thanks. have a nice day! :)

    Do you have a reference for that? Please post a mainstream textbook or peer-reviewed journal article that addresses your claims. Thanks.
