Abstract:

Up to now, silicene, one atom thick honeycomb-like arranged silicon sheet, and multilayer silicene have represented an interesting challenge either for the synthesis of new Si allotrope (2012, 108, 155501, Phys. Rev. Lett.) or the birth of the emerging topic on two-dimensional (2D) elemental materials (2018, 41, 175, Rivista del Nuovo Cimento) and 2D Van der Waals heterostructures (2013, 19, 499 Nature; 2016, 353, 6298, Science). Beyond graphene, one atom thick honeycomb arranged carbon sheet, whose discovery deserved in 2010 Physics Nobel Prize (Nobelprize.org): “For the groundbreaking experiments regarding the two-dimensional material graphene”, Silicon is the first element of group 14 manifested both exotic structural and electronic properties, showing Dirac cone and electron fermions quasiparticle behavior, nevertheless its no free standing peculiarity (2013, 102, 163106, App. Phys. Lett.; 2013, 25, 382202, J. Phys. Condens. Matter). Multilayer silicene, already synthesized on both single crystal Ag(111) (2014, 1, 0211003, 2D Materials; 2016, 3, 031011, 2D Materials) and on Si(111) after the interface formation of Si(111)-√3×√3 Ag (2017, 121, 27182, J. Phys. Chem. C), displayed the ambipolar character in the realization of the first multilayer silicene-based field effect transistor (2017, 11, 3376, ACS Nano).
