Construction of Chiral Metamaterial with a Helix Array
Xiang Xiong, Xiao-Chun Chen, Zhao-Wu Wang +5
Here we report the designing of chiral metamaterial with metallic helix array. The effective electric and magnetic dipoles, which originate from the induced surface electric curren…

Controlling growth of nanorod via screening effects
Da-Jun Shu, Xiang Xiong, Zhao-Wu Wang +3
We demonstrate in this report that nanorods can spontaneously grow on the top of a transient mound when the screening effect is considered in island growth. The number of the topmo…

Atomistic mechanisms and diameter selection during nanorod growth
Da-Jun Shu, Xiang Xiong, Zhao-Wu Wang +3
We study in this paper the atomic mechanisms of nanorod growth and propose the way of diameter selection of nanorod. A characteristic radius is demonstrated to be crucial in nanoro…
