Simultaneous Generation of Direct- and Indirect-Gap Photoluminescence in Multilayer MoS2 Bubbles
Hailan Luo, Xuanyi Li, Yanchong Zhao +12
Transition metal dichalcogenide (TMD) materials have received enormous attention due to their extraodinary optical and electrical properties, among which MoS2 is the most typical o…
Universal mechanical exfoliation of large-area 2D crystals
Yuan Huang, Yu-Hao Pan, Rong Yang +27
Two-dimensional (2D) materials provide extraordinary opportunities for exploring phenomena arising in atomically thin crystals. Beginning with the first isolation of graphene, mech…
Scanning Tunneling Microscopy Study of Square Manganese Tetramers on Mn3N2 (001)
Rong Yang, Haiqiang Yang, Arthur R. Smith
We have investigated the growth of antiferromagnetic Mn3N2(001) on MgO (001) by molecular beam epitaxy and scanning tunneling microscopy . The images show smooth terraces and atomi…
Energy Dependent Contrast in Atomic-Scale Spin-Polarized Scanning Tunneling Microscopy ofMn3N2(010): Experiment and First-Principles Theory
Rong Yang, Haiqiang Yang, Arthur R. Smith +2
The technique of spin-polarized scanning tunneling microscopy is investigated for its use in determining fine details of surface magnetic structure down to the atomic scale. As a m…
