Room temperature observation of biexcitons in exfoliated WS2 monolayers
I. Paradisanos, S. Germanis, N. T. Pelekanos +4
Single layers of WS2 are direct gap semiconductors with high photoluminescence (PL) yield holding great promise for emerging applications in optoelectronics. The spatial confinemen…
Biomimetic surface structuring using cylindrical vector femtosecond laser beams
Evangelos Skoulas, Alexandra Manousaki, Costas Fotakis +1
We report on a new, single-step and scalable method to fabricate highly ordered, multi-directional and complex surface structures that mimic the unique morphological features of ce…
Spatial Non-Uniformity in Exfoliated WS2 Single layers
I. Paradisanos, N. Pliatsikas, P. Patsalas +4
Monolayers of Transition Metal Dichalcogenides (TMDs) are atomically thin two-dimensional crystals with attractive optoelectronic properties, which are promising for emerging appli…
Gradient induced liquid motion on laser structured black Si surfaces
I. Paradisanos, C. Fotakis, S. H. Anastasiadis +1
This letter reports on the femtosecond laser fabrication of gradient-wettability micro/nano- patterns on Si surfaces. The dynamics of directional droplet spreading on the surface t…
From ripples to spikes: a hydro-dynamical physical mechanism to interpret femtosecond laser induced self-assembled structures
George D. Tsibidis, Costas Fotakis, Emmanuel Stratakis
Materials irradiated with multiple femtosecond laser pulses in sub-ablation conditions are observed to develop various types of self-assembled morphologies that range from nano-rip…
Intense femtosecond photoexcitation of bulk and monolayer MoS2
I. Paradisanos, E. Kymakis, C. Fotakis +2
The effect of femtosecond laser irradiation on bulk and single-layer MoS2 on silicon oxide is studied. Optical, Field Emission Scanning Electron Microscopy (FESEM) and Raman micros…
