Controllable Optical Negative Refraction and Phase Conjugation in Graphene
Hayk Harutyunyan, Ryan Beams, Lukas Novotny
The development of optical metamaterials has resulted in the demonstration of remarkable physical properties, including cloaking, optical magnetism, and negative refraction. The la…
Graphene Induced Surface Reconstruction of Cu
Jifa Tian, Helin Cao, Wei Wu +3
An atomic-scale study utilizing scanning tunneling microscopy (STM) in ultrahigh vacuum (UHV) is performed on large single crystalline graphene grains synthesized on Cu foil by a c…
Interface Ferromagnetism in a SrMnO3/LaMnO3 Superlattice
S. Smadici, B. B. Nelson-Cheeseman, A. Bhattacharya +1
Resonant soft x-ray absorption measurements at the O K edge on a SrMnO3/LaMnO3 superlattice show a shoulder at the energy of doped holes, which corresponds to the main peak of reso…
Antiferromagnetic Domain Wall Engineering in Chromium Films
J. M. Logan, H. C. Kim, D. Rosenmann +4
We have engineered an antiferromagnetic domain wall by utilizing a magnetic frustration effect of a thin iron cap layer deposited on a chromium film. Through lithography and wet et…
Graphene-on-Diamond Devices with Enhanced Current-Carrying Capacity: Carbon sp2-on-sp3 Technology
Jie Yu, Guanxiong Liu, Anirudha V. Sumant +2
Graphene demonstrated potential for practical applications owing to its excellent electronic and thermal properties. Typical graphene field-effect transistors and interconnects bui…
Strong Casimir force reduction through metallic surface nanostructuring
Francesco Intravaia, Stephan Koev, Il Woong Jung +6
The Casimir force between bodies in vacuum can be understood as arising from their interaction with an infinite number of fluctuating electromagnetic quantum vacuum modes, resultin…
