Tunable band gap in germanene by surface adsorption
Meng Ye, Ruge Quhe, Jiaxin Zheng +7
Opening a sizable band gap in the zero-gap germanene without heavy loss of carrier mobility is a key issue for its application in nanoelectronic devices such as high-performance fi…
Tunable Band Gap and Doping Type in Silicene by Surface Adsorption: towards Tunneling Transistors
Zeyuan Ni, Hongxia Zhong, Xinhe Jiang +4
Structural and electronic properties of silicene adsorbed by five kinds of transition metal atoms (Cu, Ag, Au, Pt, and Ir) are systematically studied by using first-principles calc…
Strong Band Hybridization between Silicene and Ag(111)Substrate
Yakun Yuan, Ruge Quhe, Jiaxin Zheng +4
By using first-principles calculations, we systematically investigated several observed phases of silicene on Ag(111) substrates and their electronic structures. We find that the o…
Tunable band gap in few-layer graphene by surface adsorption
Ruge Quhe, Jianhua Ma, Zesheng Zeng +8
There is a tunable band gap in ABC-stacked few-layer graphene (FLG) via applying a vertical electric field, but the operation of FLG-based field effect transistor (FET) requires tw…
Half-Metallic Silicene and Germanene Nanoribbons: towards High-Performance Spintronics Device
Yangyang Wang, Jiaxin Zheng, Zeyuan Ni +7
By using first-principles calculations, we predict that an in-plane homogenous electrical field can induce half-metallicity in hydrogen-terminated zigzag silicene and germanene nan…
Interfacial Properties of Bilayer and Trilayer Graphene on Metal Substrates
Jiaxin Zheng, Yangyang Wang, Lu Wang +7
One popular approach to prepare graphene is to grow them on transition metal substrates via chemical vapor deposition. By using the density functional theory with dispersion correc…
