The effect of applying an external electric field on the electronic properties of nanoporous bilayered graphene is reported. Such an effect was demonstrated on bilayered graphene structures with various types of stacking and relative arrangements of nanopores. The direct-indirect band gap transformation combined with significant changes of electronic band structure behavior was predicted. The obtained effects are of significant importance for further engineering the optical properties of such materials and open new prospects for using nanoporous bilayered graphene in electronic and optoelectronic device applications.
