High harmonic generation (HHG) in such materials offers unique platforms to develop novel optoelectronic devices at nanoscale, as well as to investigate strong-field and ultrafast nonlinear behaviour of massless Dirac fermions. However, control of HHG by modulating electronic structure of materials remains largerly unexplored to date. Here we report controllable HHG by tuning the electronic structures via mechanical engineering.
