Critical parameters for the one-dimensional systems with long-range correlated disorder (2009)
Zhao, Yi, Duan, Suqing, Zhang, Wei
We study the metal-insulator transition in a tight-binding one-dimensional (1D) model with long-range correlated disorder. In the case of diagonal disorder with site energy within...
Quantum blockade and loop current induced by a single lattice defect in graphene nanoribbons (2008)
Yan, Jie-Yun, Zhang, Ping, Sun, Bo, Lu, Hai-Zhou, Wang, Zhigang, Duan, Suqing, ...
We investigate theoretically the electronic transport properties in narrow graphene ribbons with an adatom-induced defect. It is found that the lowest conductance step of a metallic graphene...
Quasienergy spectra of a charged particle in planar honeycomb lattices (2008)
Zhang, Wei, Zhang, Ping, Duan, Suqing, Zhao, Xian-Geng
The low energy spectrum of a particle in planar honeycomb lattices is conical, which leads to the unusual electronic properties of graphene. In this letter we calculate the quasienergy spectra of a...
Photon-assistant Fano resonance in coupled multiple quantum dots (2008)
Xie, Wanyuan, Pan, Hui, Chu, Weidong, Zhang, Wei, Duan, Suqing
Based on calculations of the electronic structure of coupled multiple quantum dots, we study systemically the transport properties of the system driven by an ac electric field. We find qualitative...
Yan, Jie-Yun, Zhang, Wei, Duan, Suqing, Zhao, Xian-Geng, Govorov, Alexander O.
We investigate theoretically the effects of interaction between an optical dipole (semiconductor quantum dot or molecule) and metal nanoparticles. The calculated absorption spectra of hybrid...
Sun, Bo, Zhang, Ping, Wang, Zhigang, Duan, Suqing, Zhao, Xian-Geng, Ma, Xuchun, ...
We study the atomic oxygen adsorption on Pb(111) surface by using density-functional theory within the generalized gradient approximation and a supercell approach. The atomic and energetic properties...
Sun, Bo, Zhang, Ping, Duan, Suqing, Zhao, Xian-Geng, Shi, Junren, Xue, Qi-Kun
First-principles calculations of Cu(001) free-standing thin films have been performed to investigate the oscillatory quantum size effects exhibited in surface energy, work function, atomic...
