The disadvantage of graphene for using digital electronics is lack of bandgap, which is necessary to perform on-off switching operations in transistors. We have shown three different approaches to open a gap in graphene and tailor its electronic band structure.
The nature of the amorphous state is recognized as one of the greatest challenges of condensed matter physics in the XXI century.

Order-disorder transitions between glassy phases are quite common in nature and yet a detailed description of the structural changes entailed at microscopic scales remains elusive.
CaKFe4As4 and its variations are interesting recent additions to the Fe-based superconductors. This stoichiometric compound exhibits superconductivity below 35 K without chemical substitution.
