Electronic Structure and Magnetism in Transition Metals Doped 8-Hydroxy-Quinoline Aluminum

Chemical and electrical properties of interfaces between magnesium and aluminum and tris-„8-hydroxy quinoline... aluminum

The chemistry, electronic structure, and electron injection characteristics at interfaces formed between tris~8-hydroxy quinoline! aluminum (Alq3) and magnesium ~Mg! and aluminum ~Al! are studied via x-ray photoemission spectroscopy, ultraviolet photoemission spectroscopy, and current– voltage (I – V) measurements. Both metal-on-Alq3 and Alq3-on-metal interfaces are investigated. All interfaces...

Electronic Structure and Magnetism of Mn-Doped ZnO Nanowires

The geometric structures, electronic and magnetic properties of Mn-doped ZnO nanowires were investigated using density functional theory. The results indicated that all the calculated energy differences were negative, and the energy of the ground state was 0.229 eV lower than ferromagnetic coupling, which show higher stability in antiferromagnetic coupling. The calculated results indicated that...

Poly(p-phenylene vinylene)/tris(8-hydroxy) quinoline aluminum heterostructure light emitting diode

Results are presented from polymer/molecular organic heterostructure light emitting diodes composed of a layer of the conjugated conducting polymer poly~p-phenylene vinylene! ~PPV!, and a layer of fluorescent molecular compound tris~8-hydroxy! quinoline aluminum ~Alq!. The external quantum efficiency of these heterostructure LEDs is ;0.1%, which is over one order of magnitude higher than that o...

Structure and Electronic Properties of Transition Metal Doped Kaolinite Nanoclay

In this work, a series of transition metal (Cr, Mn, Fe, and Co) doped kaolinite nanoclays were investigated by density functional theory (DFT) calculations. The influence of metal doping on geometric structure and electronic structure of kaolinite was analyzed. The ferromagnetic (FM), antiferromagnetic (AFM), and nonmagnetic (NM) states of transition metal (TM) doped kaolinite structures were s...
