Anisotropy of the Mobility of Pentacene from Frustration
Gilles A. de Wijs, Christine C. Mattheus, Robert A. de Groot +1
The bandstructure of pentacene is calculated using first-principles density functional theory. A large anisotropy of the hole and electron effective masses within the molecular pla…
Identification of polymorphs of pentacene
Christine C. Mattheus, Anne B. Dros, Jakob Baas +4
Pentacene crystallizes in a layered structure with a herringbone arrangement within the layers. The electronic properties depend strongly on the stacking of the molecules within th…
6,13-dihydropentacene and pentacene single co-crystals
Christine C. Mattheus, Jakob Baas, Auke Meetsma +4
6,13-dihydropentacene and pentacene co-crystallise in a ratio of 2:1 during vapour transport of commercial pentacene in a gas flow. The crystal structure is monoclinic P2_1/n and c…
Disorder induced hexagonal-orthorhombic transition in (Y,Gd)MnO3
Jan-Willem Bos, Bas B. van Aken, Thomas T. M. Palstra
We show that the transition in AMnO3 from the orthorhombic perovskite phase to the hexagonal phase is promoted by inducing disorder on the A-site. The gap between the orthorhombic…
Structural view of hexagonal non-perovskite AMnO3
Bas B. van Aken, Auke Meetsma, Thomas T. M. Palstra
We refined the crystal structure of AMnO3, with A = Y, Er, Yb and Lu by single crystal x-ray diffraction. Our results show some distinct differences with previous reports on LuMnO3…
La-site shift as probe for Jahn-Teller effect
Bas B. van Aken, Auke Meetsma, Thomas T. M. Palstra
We observe two consecutive transitions in La1-xCaxMnO3, x=0.19: ferromagnetic ordering at Tc = 177 K and Jahn-Teller orbital ordering at T_JT = 150 K. The presence of a ferromagnet…
