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…
Study of electron emission from 1D nanomaterials under super high field
Chi Li, Ke Chen, Mengxue Guan +9
Photoemission driven by a strong electric field of near-infrared or visible light, referred to as strong-field photoemission, produces attosecond electron pulses that are synchroni…
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…
Band Structure Engineering of Interfacial Semiconductors Based on Atomically Thin Lead Iodide Crystals
Yan Sun, Zhen Huang, Zishu Zhou +20
To explore new constituents in two-dimensional materials and to combine their best in van der Waals heterostructures, are in great demand as being unique platform to discover new p…
Atomic Origin of Ti Deficient Dislocation in SrTiO3 Bicrystal and Their Electronic Structures
Xujing Li, Shulin Chen, Mingqiang Li +5
Dislocations in perovskite oxides have important impacts on their physical and chemical properties, which are determined by their unique atomic environments. In the present study,…
