Spatially resolved studies of the phases and morphology of methylammonium and formamidinium lead tri-halide perovskites
K. Galkowski, A. Mitioglu, A. Surrente +8
The family of organic-inorganic tri-halide perovskites including MA (MethylAmmonium)PbI, MAPbICl, FA (FormAmidinium)PbI and FAPbBr are having a trem…
Onset of exciton-exciton annihilation in single layer black phosphorus
A. Surrente, A. A. Mitioglu, K. Galkowski +5
The exciton dynamics in monolayer black phosphorus is investigated over a very wide range of photoexcited exciton densities using time resolved photoluminescence. At low excitation…
Magneto-excitons in large area CVD grown monolayer MoS and MoSe on sapphire
A. A. Mitioglu, K. Galkowski, A. Surrente +5
Magneto transmission spectroscopy was employed to study the valley Zeeman effect in large-area monolayer MoS and MoSe. The extracted values of the valley g-factors for…
Excitons in atomically thin black phosphorus
A. Surrente, A. A. Mitioglu, K. Galkowski +3
Raman scattering and photoluminescence spectroscopy are used to investigate the optical properties of single layer black phosphorus obtained by mechanical exfoliation of bulk cryst…
