Moving Targets Virtually Via Composite Optical Transformation
Wei Xiang Jiang, Tie Jun Cui
We propose a composite optical transformation to design an illusion device which can move the image of a target from one place to another place. Enclosed by such an illusion device…
An Improvement on Vizing's Conjecture
Yunjian Wu
Let denote the domination number of a graph . A {\it Roman domination function} of a graph is a function such that every vertex with 0 has a neighb…
Spinel ferrite nanocrystals embedded inside ZnO: magnetic, electronic and magneto-transport properties
Shengqiang Zhou, K. Potzger, Qingyu Xu +8
In this paper we show that spinel ferrite nanocrystals (NiFe2O4, and CoFe2O4) can be texturally embedded inside a ZnO matrix by ion implantation and post-annealing. The two kinds o…
Ferromagnetic transition metal implanted ZnO: a diluted magnetic semiconductor?
Shengqiang Zhou, K. Potzger, Qingyu Xu +7
Recently theoretical works predict that some semiconductors (e.g. ZnO) doped with magnetic ions are diluted magnetic semiconductors (DMS). In DMS magnetic ions substitute cation si…
Fast and accurate simulations of transmission-line metamaterials using transmission-matrix method
Hui Feng Ma, Tie Jun Cui, Jessie Yao Chin +1
Recently, two-dimensional (2D) periodically L and C loaded transmission-line (TL) networks have been applied to represent metamaterials. The commercial Agilent's Advanced Design Sy…
Quantum Hall Effect in Biased Bilayer Graphene
R. Ma, L. J. Zhu, L. Sheng +2
We numerically study the quantum Hall effect in biased bilayer graphene based on a tight-binding model in the presence of disorder. Integer quantum Hall plateaus with quantized con…
