Journal ArticleDOI
Interference lithographically defined and catalytically etched, large-area silicon nanocones from nanowires
M. K. Dawood,T. H. Liew,T. H. Liew,Prayudi Lianto,Minghui Hong,Sukant K. Tripathy,John T. L. Thong,John T. L. Thong,Wee Kiong Choi,Wee Kiong Choi +9 more
TL;DR: It is found that porous silicon was formed near the Au catalyst during the fabrication of the nanowires, and porous silicon exhibited enhanced oxidation ability when exposed to atmospheric conditions or in wet oxidation ambient.
Journal ArticleDOI
Realization of ∼10 nm Features on Semiconductor Surfaces via Femtosecond Laser Direct Patterning in Far Field and in Ambient Air
TL;DR: A new method is reported that enables the direct formation of 12 nm (λ/66) features on silicon surfaces via the irradiation of orthogonally polarized double femtosecond laser beams.
Proceedings ArticleDOI
Laser precision engineering from microfabrication to nanoprocessing
TL;DR: In this paper, a laser nanofabrication will play a much more important role in the next generation manufacturing, which has unique advantages of noncontact process, flexible setup and high speed processing in air.
Journal ArticleDOI
Quasi-Talbot effect of orbital angular momentum beams for generation of optical vortex arrays by multiplexing metasurface design
Hui Gao,Hui Gao,Yang Li,Lianwei Chen,Jinjin Jin,Mingbo Pu,Xiong Li,Ping Gao,Changtao Wang,Xiangang Luo,Minghui Hong +10 more
TL;DR: The agreement between the numerical and measured results suggests the practicability of this method to realize vortex beam arrays with high integrated levels, which can open a new door to achieve various potential uses related to optical vortex arrays in integrated optical systems for wide-ranging applications.
Journal ArticleDOI
A broadband acoustic metamaterial with impedance matching layer of gradient index
Yihang Ding,Yihang Ding,Eleftherios Christos Statharas,Eleftherios Christos Statharas,Kui Yao,Minghui Hong +5 more
TL;DR: In this paper, a broadband acoustic metamaterial comprising a space coiling structure was proposed and demonstrated by introducing an impedance-matching layer between air and the metammaterial, which is achieved by especially designing the parameters of the space-coiling structure to form a gradient index.
