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…

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…
