Spin-polarized transport in II–VI magnetic resonant tunneling devices

We investigate electronic transport through II–VI semiconductor resonant tunneling structures containing diluted magnetic impurities. Due to the exchange interaction between the conduction electrons and the impurities, there arises a giant Zeeman splitting in the presence of a moderately low magnetic field. As a consequence, when the quantum well is magnetically doped the current–voltage charac...

Spin-polarized resonant tunneling in magnetic tunnel junctions.

Insertion of a thin nonmagnetic copper Cu(001) layer between the tunnel barrier and the ferromagnetic electrode of a magnetic tunnel junction is shown to result in the oscillation of the tunnel magnetoresistance as a function of the Cu layer thickness. The effect is interpreted in terms of the formation of spin-polarized resonant tunneling. The amplitude of the oscillation is so large that even...

Resonant tunneling diode circuits using Pspice

The measured I –V data and the large-signal equivalent circuit of a resonant tunneling diode are exploited, through the analog behavioral modeling capabilities of Pspice, to create a Pspice compatible model for the diode. The model is used, with very few other components, in the simulation of a number of circuit applications including a sinusoidal wave generator, a frequency multiplier and thre...
