abstract = {We propose a reconfigurable magnetic tunnel diode and
transistor based on half-metallic magnets (HMMs) and spin
gapless semiconductors (SGSs). The two-terminal tunnel diode
is composed of a HMM electrode and a SGS electrode separated
by a thin insulating (I) tunnel barrier. Depending on the
relative orientation of the magnetization of the electrodes,
the magnetic tunnel diode allows the electrical current to
pass in either one or the other direction. The
three-terminal magnetic tunnel transistor consists of a
HMM-I-SGS-I-HMM (emitter–base–collector) structure and
can be switched on and off by application of a voltage to
the base electrode and conducts current in both directions
similar to conventional field-effect transistors. The unique
energy band structure of the SGS-I-HMM junction prevents
base–collector leakage currents and allows dual-mode
operation of the transistor. Both devices can be configured
by an external magnetic field or by the spin transfer torque
switching. By employing the nonequilibrium Green’s
function method combined with density functional theory, we
demonstrate the reconfigurable rectification characteristics
of the proposed diode based on sp-electron materials.},
