Multielectron Bubbles : A Curved Two-dimensional Electron System in Confinement
(2018-06-15)Electrons are weakly attracted to liquid helium due to the small but finite polarizability of helium atoms. However, they cannot enter the liquid unless their energy is more than 1 eV, due to the Pauli exclusion principle. ... -
Optical and Electrical Studies of Hybrid Nanomaterial Composites Based on Noble Metal Nanostructures
Localized surface plasmon resonance (LSPR) in noble metal nanoparticles like gold (Au) and silver (Ag) results in enhancements in optical absorption and scattering by the nanoparticles, accompanied by a dramatic ... -
