Strong Second Harmonic Generation from Bilayer Graphene with Symmetry Breaking by Redox-Governed Charge Doping
Mingwen Zhang, Nannan Han, Jing Wang +5
Missing second-order nonlinearity in centrosymmetric graphene overshadows its intriguing optical attribute. Here, we report redox-governed charge doping could effectively break the…
Layer-by-layer growth of bilayer graphene single-crystals enabled by self-transmitting catalytic activity
Zhihong Zhang, Linwei Zhou, Zhaoxi Chen +23
Direct growth of large-area vertically stacked two-dimensional (2D) van der Waal (vdW) materials is a prerequisite for their high-end applications in integrated electronics, optoel…
Electrical probing of COVID-19 spike protein receptor binding domain via a graphene field-effect transistor
Xiaoyan Zhang, Qige Qi, Qiushi Jing +9
Here, in an effort towards facile and fast screening/diagnosis of novel coronavirus disease 2019 (COVID-19), we combined the unprecedently sensitive graphene field-effect transisto…
Doping Induced Second Harmonic Generation in Centrosymmetric Graphene from Quadrupole Response
Yu Zhang, Di Huang, Yuwei Shan +8
For centrosymmetric materials such as monolayer graphene, no optical second harmonic generation (SHG) is generally expected because it is forbidden under the electric-dipole approx…
Towards the growth of single-crystal boron nitride monolayer on Cu
Li Wang, Xiaozhi Xu, Leining Zhang +21
Atom-layered hexagonal boron nitride (hBN), with excellent stability, flat surface and large bandgap, has been reported to be the best 2D insulator to open up the great possibiliti…
Gate tunable third-order nonlinear optical response of massless Dirac fermions in graphene
Tao Jiang, Di Huang, Jinluo Cheng +13
Materials with massless Dirac fermions can possess exceptionally strong and widely tunable optical nonlinearities. Experiments on graphene monolayer have indeed found very large th…
Ultrafast Epitaxial Growth of Metre-Sized Single-Crystal Graphene on Industrial Cu Foil
Xiaozhi Xu, Zhihong Zhang, Jichen Dong +20
A foundation of the modern technology that uses single-crystal silicon has been the growth of high-quality single-crystal Si ingots with diameters up to 12 inches or larger. For ma…
