Structural effects on electronic properties of selected materials

Tuning structural properties, e.g., by means of external pressure or applied uniaxial strain, can significantly modify the electronic properties of several solid systems, thereby influencing, or even inducing, several electronic instabilities. We specifically analyze the effect of pressure or strain on several superconducting materials, including the high-(T_c) cuprates , some organic salts, and magnesium diboride, on the light alkalis, where pressure can even destroy metallicity, and graphene , whose remarkable electronic and transport properties can be tailored by applied strain.
