in this paper we have solved analytically the schrödinger equation for a microscopic particle in a one-dimensional box with two infinite walls, which the potential function inside it, has a linear form. based on the solutions of this special quantum mechanical system, we have shown that as the quantum number approaches infinity the expectation values of microscopic particle position and square ...

a comprehensive study of schottky barrier mosfet (sbmosfet) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within non-equilibrium green's function formalism. quantum confinement increases the effective schottky barrier height (sbh). (100) orientation provides lower effective schottky barrier height in comparison ...

various synthesis methods have been proposed in the literature for reversible and quantum logic circuits. however, there are few algorithms to optimize an existing circuit with multiple constraints simultaneously. in this paper, some heuristics in genetic algorithms (ga) to optimize a given circuit in terms of quantum cost, number of gates, location of garbage outputs, and delay, are proposed. ...

in the recent work, the reaction mechanism between triphenylphosphine 1, dialkyl acetylenedicarboxylates 2 in the presence of nh-acid, such as 5-aminoindazole 3 were investigated theoretically. quantum mechanical studies were performed for evaluation of potential energy surfaces of all structures participated in the reaction mechanism both in gas phase and in dichloromethane. the first step of ...

in the present study we focused on the electronic and structural properties of na and mg adsorption on the surface of the (6, 6) armchair sicnts. the adsorption energy (eads), band gap energy (eg), partial density of state (pdos), chemical potential (μ), global hardness (η), electrophilicity index (ω), global softness (s), work function values (φ) and work function change (δφ) are calculated by...

the controversial theories of modern physics created a remarkable revolution in twentieth-century literature. the progressive novelists of the century, inspired by the concepts in quantum mechanics, expressed the concerns of living in the modern world in the form of non-linear, heterogeneous writing based on doubt. in his autobiographical work, entitled w or the childhood memory, george perec p...

a quantum theory of a two and three-level laser with injected atomic coherence is developed by using a density operator method, to the best of our knowledge, for the first time. the initial atomic coherence plays an essential role. at steady state, the equation of motion for the density operator yields to exhibit laser without inversion and a phase locking but no threshold for the laser field. ...

the fabrication of a non-doped red organic light-emitting device (oled) has been developed using naturally occurring curcumin as an emissive layer of oled. in this research, the electroluminescent spectrum (el) of curcumin as a donor-acceptor-donor (d-a-d) chromophore was obtained at wavelength of 612 nm. also, the maximum external quantum efficiencies (eqe) for this device was measured and fou...

at the present study, different properties of sarin with the formula [(ch3)2cho]ch3pof was studiedin gas phase. geometrical optimizations of sarin, single point calculation, nmr and electricalparameters were carried out in gas phase with the hartee -fock method coupled to 6-31g* basis setsfor all atoms. the results obtained from a comparison between tables and charts came up fordiscussion and a...
