Photoemission intermittency via stochastic gating in rubrene nanowires coupled to plasmonic silver nanoparticles
Moha Naeimi, Waqas Pervez, Frithjof Harmsen +2
In this work, we report a new nanoscale phenomenon observed as photoemission intermittency (On-Off electron emission), manifested as stochastic bursts in electron yield at quasi-on…
Dual-wavelength control of charge accumulation in rubrene microcrystals with anisotropic conductivity
Moha Naeimi, Ingo Barke, Sylvia Speller
Previously, a novel type of rubrene microcrystals was reported, forming two distinct sectors -- diamond- and triangular-shaped -- that exhibit pronounced contrasts in photoluminesc…
Zone-sectored organic crystals with spatially resolved exciton dynamics
Moha Naeimi, Tim Völzer, Regina Lange +4
Among the organic semiconductors, rubrene stands out in terms of hole mobility, luminescence yield and exciton migration distance. A novel type of rubrene microcrystal is prepared…
Plasmon-assisted photoelectron emission in a model cluster using time-dependent density functional theory and the time-dependent surface-flux method
Mikhail Bednov, Waqas Pervez, Ingo Barke +1
We investigate plasmon-assisted photoelectron emission using a one-dimensional time-dependent density-functional theory (TDDFT) model. Photoelectron spectra are computed with the t…
Imaging domain boundaries of rubrene thin crystallites by photoemission electron microscopy
Moha Naeimi, Katharina Engster, Waqas Pervez +2
The progress of designing organic semiconductors is extensively dependent on the quality of prepared organic molecular assemblies, since the charge transport mechanism is strongly…
Morphology and structural properties of thin rubrene crystallites grown on graphite
Moha Naeimi, Katharina Engster, Ingo Barke +1
Crystallization of rubrene, progressing from an amorphous phase to a triclinic meta-stable and ultimately to the orthorhombic stable phase, offers broad applications not only in or…
