Influence of oxygen annealing conditions on the electronic structure, dielectric function, and charge conduction of gallium-ferrite thin films
Gallium-ferrite thin films were studied to investigate the effects of the oxygen annealing conditions on the electrical properties. Ga0.8Fe1.2O3−δ thin films were prepared by using a sol-gel meth...

Electric-magnetic duality implies (global) conformal invariance
We have examined quantum theories of electric-magnetic duality-invariant vector fields enjoying classical conformal invariance in 4-dimensional flat spacetime. We extend Dirac’s argument about “the conditions ...

Electrical Properties of MoS2 Field-Effect Transistors in Contact with Layered CrPS4
We report the enhanced electrical performance of a MoS2 field-effect transistor (FET) by using a contact with a layered CrPS4. Our transport measurements revealed that MoS2 channel with CrPS4 junction showed high...

Ripples, Wrinkles, and Crumples in Folded Graphene
Separation of two-dimensional thin-film-materials into single layers had been considered very challenging both theoretically and experimentally until the mechanical exfoliation method was discovered. After the...

Spatiotemporal behaviors of the ridership of a public transportation system during an epidemic outbreak: case of MERS in Seoul
During May and June 2015, an outbreak of the Middle East respiratory syndrome (MERS) occurred in Korea, which raised the fear of contagion throughout society and suppressed the use of public transportation sys...
