Outline of Final Research Achievements

The electronic structures and physical properties of low-dimensional nano-structures formed on solid surface have been investigated both experimentally and theoretically. The addition of valley degree of freedom by controlling the symmetry of the nano-structures, leads to the observation of extraordinary Rashba effect, such as non-vortical valley spin structure and 100 % spin polarized metallic valley structure. These effects, which are concluded to result from the lack of either the rotational symmetry or the mirror symmetry, suppress the backscattering probability of electron spins and thus open a great avenue to realize semiconductor spintronics devices. We also succeeded to form a two-dimensional honeycomb network with cyclic thiazyl biradical molecules, and showed this honeycomb network to have Dirac fermion and thus to behave like a molecular graphene.
