Journal ArticleDOI
Highly electrically conductive layered carbon derived from polydopamine and its functions in SnO2-based lithium ion battery anodes
Junhua Kong,Wu Aik Yee,Liping Yang,Yuefan Wei,Si Lei Phua,Hock Guan Ong,Jia Ming Ang,Xu Li,Xuehong Lu +8 more
TL;DR: Thin carbonized polydopamine (C-PDA) coatings are found to have similar structures and electrical conductivities to those of multilayered graphene doped with heteroatoms.
Journal ArticleDOI
All-carbon electronic devices fabricated by directly grown single-walled carbon nanotubes on reduced graphene oxide electrodes
Bing Li,Xiehong Cao,Hock Guan Ong,Jun Wei Cheah,Xiaozhu Zhou,Zongyou Yin,Hai Li,Junling Wang,Freddy Yin Chiang Boey,Wei Huang,Hua Zhang +10 more
TL;DR: The second strategy possesses some advantages, such as no CNT purifi cation and no photolithography required, which could be a better choice to produce clean and high-performance CNT-based devices, since the pristine structures and intrinsic properties of the grown CNTs are preserved.
Journal ArticleDOI
Oxygen Vacancy Induced Room-Temperature Metal–Insulator Transition in Nickelate Films and Its Potential Application in Photovoltaics
Le Wang,S. Dash,Lei Chang,Lu You,Yaqing Feng,Xu He,Kui Juan Jin,Yang Zhou,Hock Guan Ong,Peng Ren,Shiwei Wang,Lang Chen,Junling Wang +12 more
TL;DR: In this paper, the authors demonstrate reversible control of oxygen content by postannealing at temperature lower than 300 °C and realize the reversible metal-insulator transition in epitaxial NdNiO3 films.

Oxygen vacancy induced room temperature metal-insulator transition in nickelates films and its potential application in photovoltaics
Le Wang,S. Dash,Lei Chang,Lu You,Yaqing Feng,Xu He,Kuijuan Jin,Yang Zhou,Hock Guan Ong,Peng Ren,Shiwei Wang,Lang Chen,Junling Wang +12 more
TL;DR: Reversible control of oxygen content by postannealing at temperature lower than 300 °C is demonstrated and the reversible metal-insulator transition in epitaxial NdNiO₃ films is realized and opens up new possibilities for strongly correlated perovskite nickelates.
Journal ArticleDOI
Self-Assembled Shape- and Orientation-Controlled Synthesis of Nanoscale Cu3Si Triangles, Squares, and Wires
Zhou Zhang,Lai Mun Wong,Hock Guan Ong,Xin Jiao Wang,Junling Wang,Shijie Wang,Hongyu Chen,Tom Wu +7 more
TL;DR: In this work, nanoscale Cu3Si triangles, squares, and wires have been grown on Si(111), (100), and (110) substrates, respectively, through a template-free Au-nanoparticle-assisted vapor transport method, using Au nanoparticles to absorb Cu vapor and facilitate the rate-limited diffusion of Si.
