The Hidden Cost of Alloying: Disorder-Driven Transport Collapse in TMDs
Michele Pisarra, Clara Rebanal, Enrique Arévalo Rodríguez +19
Alloying in two dimensional semiconductors is widely used to tune bandgaps, yet its implications for charge and energy transport remain poorly understood. Here, we investigate MoS2…
Bandgap Engineering On Demand in GaAsN Nanowires by Post-Growth HydrogennImplantation
Nadine Denis, Akant Sharma, Elena Blundo +9
Bandgap engineering in semiconductors is required for the development of photonic and optoelectronic devices with optimized absorption and emission energies. This is usually achiev…
Ferroelectric Control of Interlayer Excitons in 3R-MoS / MoSe Heterostructures
Johannes Schwandt-Krause, Mohammed El Amine Miloudi, Elena Blundo +9
We investigate the interaction between interlayer excitons and ferroelectric domains in hBN-encapsulated 3R-MoS/MoSe heterostructures, combining photoluminescence experimen…
Extremely high excitonic -factors in 2D crystals by alloy-induced admixing of band states
Katarzyna Olkowska-Pucko, Tomasz Woźniak, Elena Blundo +24
Monolayers (MLs) of semiconducting transition metal dichalcogenides (\mbox{S-TMDs}) emit light very efficiently and display rich spin-valley physics, with gyromagnetic (-) facto…
Giant light emission enhancement in strain-engineered InSe/MS (M=Mo,W) van der Waals heterostructures
Elena Blundo, Marzia Cuccu, Federico Tuzi +11
Two-dimensional crystals stack together through weak van der Waals (vdW) forces, offering unlimited possibilities to play with layer number, order and twist angle in vdW heterostru…
Fine-Tuning of the Excitonic Response in Monolayer WS2 Domes via Coupled Pressure and Strain Variation
Elena Stellino, Beatrice D'Alò, Elena Blundo +2
We present a spectroscopic investigation into the vibrational and optoelectronic properties of WS2 domes in the 0-0.65 GPa range. The pressure evolution of the system morphology, d…
Localisation-to-delocalisation transition of moiré excitons in WSe/MoSe heterostructures
Elena Blundo, Federico Tuzi, Salvatore Cianci +12
Moiré excitons (MXs) are electron-hole pairs localised by the periodic (moiré) potential forming in two-dimensional heterostructures (HSs). MXs can be exploited, , for creati…
Variant Plateau Law in Atomically Thin Transition Metal Dichalcogenide Dome Networks
Boqing Liu, Tanju Yildirim, Tieyu Lv +10
Since its fundamental inception from soap bubbles, Plateau law has sparked extensive research in equilibrated states. However, most studies primarily relied on liquids, foams or ce…
Variation of the fundamental band gap nature in curved two-dimensional WS2
E. Blundo, M. Felici, T. Yildirim +7
We report a strain-induced direct-to-indirect band gap transition in mechanically deformed WS2 monolayers (MLs). The necessary amount of strain is attained by proton irradiation of…
Proton-driven patterning of bulk transition metal dichalcogenides
Davide Tedeschi, Marco Felici, Giorgio Pettinari +6
At the few-atom-thick limit, transition metal dichalcogenides (TMDs) exhibit a host of attractive electronic optical, and structural properties. The possibility to pattern these pr…
