Experimental and Theoretical NANOTECHNOLOGY (ETN) abbreviated as Exp. Theo. NANOTECHNOLOGY is a multidisciplinary peer-reviewed and open access journal. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of nanotechnology with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics, materials science and medicine. ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.



Electronic band structures and charge densities of GaN, AlN, and their alloy Ga0.5Al0.5N in zinc-blende structure using empirical pseudopotential method are investigated. For the Ga1-xAlxN ternary alloy, the virtual crystal approximation is coupled with the pseudopotential method. The energies along f, X, and L of Ga1-xAlxN alloy as a function of the alloy concentration is calculated. Angular correlation of positron annihilation radiation along different crystallographic directions in GaN, AlN, and Ga0.5Al0.5N is calculated. Other quantities such as ionicity character and bulk modulus by means of recent models with respect to the alloy concentration are discussed.
