MEMS approach to low-frequency broadband acoustic metamaterials
Lixiang Wu, Quansheng Sun, Qifa Zhou +1
We experimentally demonstrate a simple micro-electro-mechnical systems (MEMS) approach to acoustic metamaterials and have observed the average increase of nearly 6 dB beyond the cl…
Mechanism of substrate-induced anisotropic growth of monolayer WS2 by kinetic Monte Carlo simulations
Lixiang Wu, Weihuang Yang, Gaofeng Wang
Controlled anisotropic growth of two-dimensional materials provides an approach for the synthesis of large single crystals and nanoribbons, which are promising for applications as…
Surface modeling for optical fabrication with linear ion source
Lixiang Wu, Chaoyang Wei, Jianda Shao
We present a concept of surface decomposition extended from double Fourier series to nonnegative sinusoidal wave surfaces, on the basis of which linear ion sources apply to the ult…
Fine-tuning the etch depth profile via dynamic shielding of ion beam
Lixiang Wu, Keqiang Qiu, Shaojun Fu
We introduce a method for finely adjusting the etch depth profile by dynamic shielding in the course of ion beam etching (IBE), which is crucial for the ultra-precision fabrication…
Variable-spot ion beam figuring
Lixiang Wu, Keqiang Qiu, Shaojun Fu
This paper introduces a new scheme of ion beam figuring (IBF), or rather variable-spot IBF, which is conducted at a constant scanning velocity with variable-spot ion beam collimate…
