    TUNNEL MAGNETORESISTANCE OF AN ORGANIC MOLECULE junction 

    Type: Conference Paper
    Author : مجتبی اشهدی; ناصر شاه طهماسبی; مصطفی عسگری فرسنگی; داود واحدی فخرآباد; mojtaba ashhdi; Nasser Shahtahmassebi; mostafa asgarifarsangi; davoud vahedi fakhrabad
    Year: 2010
    Abstract:

    (Fig. 1).

    The work is based on the tight-binding Hamiltonian model and within the

    framework of a non-equilibrium Green’s function (NEGF) technique. It is shown

    that tunnel magnetoresistance (TMR) of molecular junction can be large...

    TUNNELING MAGNETORESISTANCE OF POLYACENE-BASE MAGNETIC JUNCTIONS 

    Type: Conference Paper

    Year: 2010
    Abstract:

    In this work, using a tight-binding Hamiltonian and a non-equilibrium Green's

    function technique, the spin-dependent transport properties of the electrode/ single

    Year: 2010
    Abstract:

    Abstract. Coherent spin-dependent electronic transport is investigated in a molecular junction

    based on oligophenylene attached to two the semi-infinite ferromagnetic (FM) electrodes with

    finite cross sections. ...

    Year: 2010
    Abstract:

    a b s t r a c t

    Based on a p-orbital tight-binding model Hamiltonian and the Green’s function approach together with

    the Landauer formalism, we studied the coherent spin-dependent transport properties of ...

    Year: 2011
    Abstract:

    In this research, we have studied the effect of inelastic electron–phonon interactions on current–voltage

    characteristic and tunneling magnetoresistance of a polythiophene molecule that is sandwiched between

    two cobalt electrodes using...
