Chaoliang Tan,Xiehong Cao,Xiehong Cao,Xue-Jun Wu,Qiyuan He,Jian Yang,Xiao Zhang,Junze Chen,Wei Zhao,Shikui Han,Gwang-Hyeon Nam,Melinda Sindoro,Hua Zhang +12 more
TL;DR: The unique advances on ultrathin 2D nanomaterials are introduced, followed by the description of their composition and crystal structures, and the assortments of their synthetic methods are summarized.
Journal ArticleDOI
Graphene-Based Materials: Synthesis, Characterization, Properties, and Applications
Xiao Huang,Zongyou Yin,Shixin Wu,Xiaoying Qi,Qiyuan He,Qichun Zhang,Qingyu Yan,Freddy Yin Chiang Boey,Hua Zhang +8 more
TL;DR: The synthesis, characterization, properties, and applications of graphene-based materials are discussed and the promising properties together with the ease of processibility and functionalization make graphene- based materials ideal candidates for incorporation into a variety of functional materials.
Journal ArticleDOI
Single‐Layer Semiconducting Nanosheets: High‐Yield Preparation and Device Fabrication
Zhiyuan Zeng,Zongyou Yin,Xiao Huang,Hai Li,Qiyuan He,Gang Lu,Freddy Yin Chiang Boey,Hua Zhang +7 more
TL;DR: The common feature of these materials is that the bulk material forms are layeredstructures with strong covalent bonding in each layer and weak van der Waals forces between the layers.
Journal ArticleDOI
Fabrication of Single‐ and Multilayer MoS2 Film‐Based Field‐Effect Transistors for Sensing NO at Room Temperature
Hai Li,Zongyou Yin,Qiyuan He,Hong Li,Xiao Huang,Gang Lu,Derrick Wen Hui Fam,Alfred Iing Yoong Tok,Qing Zhang,Hua Zhang +9 more
TL;DR: Although the single-layer MoS(2) device shows a rapid response after exposure to NO, the current was found to be unstable, and these FET devices can be used as gas sensors to detect nitrous oxide.
Journal ArticleDOI
Fabrication of flexible MoS2 thin-film transistor arrays for practical gas-sensing applications.
TL;DR: This flexible transistor array can be used as a highly sensitive gas sensor with excellent reproducibility and functionalization of the MoS(2) thin film with Pt nanoparticles further increases the sensitivity by up to ∼3 times.
