Abstract A comprehensive overview of density functional theory simulations of high-k oxide/III-V semiconductor interfaces is presented. The methodologies of realistic amorphous high-k oxide generation by hybrid classical-DFT molecular dynamics are compared. The simulation techniques, oxide/semiconductor model designs and rules for formation of unpinned high-k oxide/semiconductor interfaces are ...

The label semiconductor itself provides a hint as to its characteristics. The prefix semis normally applied to a range of levels midway between two limits. The term conductor is applied to any material that will support a generous flow of charge when a voltage source of limited magnitude is applied across its terminals. An insulator is a material that offers a very low level of conductivity und...

innovation &IN THE NANOSCALE regime, speed and density of semiconductor technology continue to increase. However, skyrocketing design costs for developing gigascale system chips have effectively slowed the creation of new design projects. Such a trend could stifle further innovation and advancement in the semiconductor industry. A recent joint report from the Semiconductor Research Corporation ...

Ballistic spin polarized transport through diluted magnetic semiconductor single and double barrier structures is investigated theoretically using a two-component model. The tunneling magnetoresistance ~TMR! of the system exhibits oscillating behavior when the magnetic field is varied. An interesting beat pattern in the TMR and spin polarization is found for different nonmagnetic semiconductor/...
