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...

We show that a metal-dielectric-metal structure can function as a negative refraction lens for surface plasmon waves on a metal surface. The structure is uniform with respect to a plane of incidence and operates at the optical frequency range. Using three-dimensional finite-difference time-domain simulations, we demonstrate the imaging operation of the structure with realistic material paramete...

This  article  provides  an  overview  on  preparation,  design,  crystal structure  and  properties  of  some  metal-organic  frameworks  of carboxylate coordination polymers mixed with pyridine-functionality linkers  prepared  in  our  laboratory.  The  article  covers  coordination polymers  in  two-  and  three-dimensional  supramolecular architectures. The reported coordination polyme...
