Silicene and germanene are novel allotropes of silicon and germanium and the counterparts of graphene . They are predicted to be two-dimensional topological insulators, respectively up to about 10K and nearly room temperature. The mobilities of their charge carriers are expected to be very high, potentially exceeding those of graphene for the latter. After describing our realization of epitaxial single  and multilayer silicene on silver (111) substrates , I will present hints of the synthesis of epitaxial germanene, a novel germanium allotrope that does not exist in nature . I will further review fundamental results on these novel two-dimensional materials, which might open the way to tantalizing applications.
