Spin splitting of Dirac fermions in graphene on Ni intercalated with alloy of Bi and Au

Weak localization of bismuth cluster-decorated graphene and its spin–orbit interaction

“…The Rashba spin splitting of the Dirac cone is nearly zero. This is ascribed to the peculiar electronic structure of Bi, which has a valence band with no d electronic states responsible for the onset of giant Rashba effect through electronic hybridization with the π band of graphene [35]. Thus, it is reasonable for us to only consider the influence of the Kane-Mele SOC on the WL.…”

Growth of graphene monolayer by “internal solid-state carbon source”: Electronic structure, morphology and Au intercalation

“…The most popular methods used now are the methods of mechanical exfoliation from a graphite monocrystal [1][2][3], catalytic reaction of cracking of carbonaceous gases on the surface of monocrystals and monocrystalline films of transition metals [8][9][10][11][12][13][14][15], and the method of thermal carbidization of silicon carbide (SiC) monocrystals [16,17]. At the present moment the method of cracking of carbon-contained gases (like propylene (C 3 H 6 )) on the surface of Ni(111) monocrystalline film is widely spread due to its simplicity and a very small mismatch between graphene and Ni(111) lattice parameters.…”

“…At the present moment the method of cracking of carbon-contained gases (like propylene (C 3 H 6 )) on the surface of Ni(111) monocrystalline film is widely spread due to its simplicity and a very small mismatch between graphene and Ni(111) lattice parameters. As a result, an epitaxial well-ordered graphene with monolayer thickness is formed atop Ni(111) [8][9][10][11][12][13][14][15]. It is well-known [11,12] that the catalytic reaction of cracking of carbonaceous gases is self-limited and stops when a whole Ni(111) surface is covered by a monolayer graphene (MG).…”

Адсорбция никеля на поверхности Bi-=SUB=-2-=/SUB=-Se-=SUB=-3-=/SUB=-

“…Будучи в объеме диэлектриками с широкой запрещенной зоной, на поверхности у них имеются поверхностные состояния, обладающие топологически-ми свойствами [1][2][3]. Как и у графена дисперсионная зависимость имеет форму конуса [4], но в отличие от графена он располагается в центре зоны Бриллюэна. Блокирование степеней свободы по спину и моменту ко-личества движения приводит к невозможности упругого рассеяния электронов и изменения направления спина.…”
