Raman Characterization of Platinum Diselenide Thin Films
Maria O'Brien, Niall McEvoy, Carlo Motta +12
Platinum diselenide (PtSe2) is a newly discovered 2D material which is of great interest for applications in electronics and catalysis. PtSe2 films were synthesized by thermally-as…
Mapping of Low-Frequency Raman Modes in CVD-Grown Transition Metal Dichalcogenides: Layer Number, Stacking Orientation and Resonant Effects
Maria OBrien, Niall McEvoy, Damien Hanlon +3
Layered inorganic materials, such as the transition metal dichalcogenides (TMDs), have attracted much attention due to their exceptional electronic and optical properties. Reliable…
Low wavenumber Raman spectroscopy of highly crystalline MoSe2 grown by chemical vapor deposition
Maria O'Brien, Niall McEvoy, Damien Hanlon +4
Transition metal dichalcogenides (TMDs) have recently attracted attention due to their interesting electronic and optical properties. Fabrication of these materials in a reliable a…
Direct Observationof DegenerateTwo-Photon Absorption and Its Saturation in WS2 and MoS2 Monolayer and Few-Layer Films
Saifeng Zhang, Ningning Dong, Niall McEvoy +10
The optical nonlinearity of WS2, MoS2 monolayer and few-layer films was investigated using the Z-scan technique with femtosecond pulses from the visible to the near infrared. The d…
