Probing Many-Body Interactions in Monolayer Transition-Metal Dichalcogenides

, 2019
Many-body interactions in monolayer transition-metal dichalcogenides are strongly affected by their unique band structure. We study these interactions by measuring the energy shift of neutral excitons (bound electron-hole pairs) in gated WSe$_2$ and MoSe$

Blue luminescence of Au nanoclusters embedded in silica matrix

, 2004
Photoluminescence study using the 325 nm He-Cd excitation is reported for the Au nanoclusters embedded in SiO2 matrix. Au clusters are grown by ion beam mixing with 100 KeV Ar+ irradiation on Au [40 nm]/SiO2 at various fluences and subsequent annealing ...

Gate-induced blueshift and quenching of photoluminescence in suspended single-walled carbon nanotubes [PDF]

, 2011
Gate-voltage effects on photoluminescence spectra of suspended single-walled carbon nanotubes are investigated. Photoluminescence microscopy and excitation spectroscopy are used to identify individual nanotubes and to determine their chiralities.
