Crossover from spin accumulation into interface states to spin injection in the germanium conduction band.
Electrical spin injection into semiconductors paves the way for exploring new phenomena in the area of spin physics and new generations of spintronic devices. However the exact role of interface states in the spin injection mechanism from a magnetic tunnel junction into a semiconductor is still under debate. In this Letter, we demonstrate a clear transition from spin accumulation into interface...
متن کاملThe Role of Interface States in Controlling the Electronic Structure of Alq 3 /reactive Metal Contacts
Gap states induced by the formation of metal/organic interfaces have been observed in a number of instances. Yet, the role that these states play in determining the electronic structure of the interface and the carrier injection barriers has not been clearly established. In this paper, we provide a model for the role of chemistry-induced gap states at Mg/ Alq 3 and Al/Alq 3 interfaces, in parti...
متن کاملElectronic and spin properties of hole point contacts
We have studied theoretically the effect of a tuneable lateral confinement on two-dimensional hole systems realised in III-V semiconductor heterostructures. Based on the 4 × 4 Luttinger description of the valence band, we have calculated quasi-onedimensional (quasi-1D) hole subband energies and anisotropic Landé g-factors. Confinement-induced band mixing results in the possibility to manipulate...
