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…
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…
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…
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…
