Magnetism in MoS2 induced by MeV proton irradiation
S. Mathew, K. Gopinadhan, T. K. Chan +9
Molybdenum disulphide, a diamagnetic layered dichalcogenide solid, is found to show magnetic ordering at room temperature when exposed to a 2 MeV proton beam. The temperature depen…
ATHENA Detector Proposal -- A Totally Hermetic Electron Nucleus Apparatus proposed for IP6 at the Electron-Ion Collider
ATHENA Collaboration, J. Adam, L. Adamczyk +433
ATHENA has been designed as a general purpose detector capable of delivering the full scientific scope of the Electron-Ion Collider. Careful technology choices provide fine trackin…
Measuring the magnetic dipole transition of single nanorods by spectroscopy and Fourier microscopy
R. Chacon, A. Leray, J. Kim +6
Rare-earth doped nanocrystals possess optical transitions with significant either electric or magnetic dipole characters. They are of strong interest for understanding and engineer…
Vectorial probing of electric and magnetic transitions in variable optical environments and vice-versa
R. Chacon, A. Leray, J. Kim +6
We use europium doped single crystalline NaYF nanorods for probing the electric and magnetic contributions to the local density of optical states (LDOS). Reciprocically, we det…
The effect of layer number and substrate on the stability of graphene under MeV proton beam irradiation
S. Mathew, T. K. Chan, D. Zhan +7
The use of graphene electronics in space will depend on the radiation hardness of graphene. The damage threshold of graphene samples, subjected to 2 MeV proton irradiation, was fou…
Structure and lattice dynamics of the wide band gap semiconductors MgSiN and MgGeN
M. RÃ¥sander, J. B. Quirk, T. Wang +4
We have determined the structural and lattice dynamical properties of the orthorhombic, wide band gap semiconductors MgSiN and MgGeN using density functional theory. In…
Source region of the 2003 November 18 CME that led to the strongest magnetic storm of cycle 23
N. Srivastava, S. Mathew, R. Louis +1
The super-storm of November 20, 2003 was associated with a high speed coronal mass ejection which originated in the NOAA AR 10501 on November 18. This coronal mass ejection had sev…
Growth of narrow-neck, epitaxial and nearly spherical Ge nanoislands on air-exposed Si(111)-(77) surfaces
K. Bhattacharjee, A. Roy, S. Roy +4
Growth of narrow-neck, epitaxial as well as non-epitaxial and nearly spherical Ge islands on air-exposed Si(111)-(7\times7) surfaces has been investigated by in-situ scanning tunne…
Magnetism in C60 Films Induced by Proton Irradiation
S. Mathew, B. Satpati, B. Joseph +3
It is shown that polycrystalline fullerene thin films on hydrogen passivated Si(111) substrates irradiated by 2 MeV protons displays ferromagnetic-like behavior at 5 K. At 300 K bo…
