TL;DR: Being optically transparent with the above optimal properties, Cr-doped In2O3 emerges as a viable candidate for the development of spin electronics.
Journal ArticleDOI
Room-temperature tunnel magnetoresistance and spin-polarized tunneling through an organic semiconductor barrier.

TL;DR: Spin polarization (P) of the tunnel current through the Alq3 layer, directly measured using superconducting Al as the spin detector, shows that minimizing formation of an interfacial dipole layer between the metal electrode and organic barrier significantly improves spin transport.
Journal ArticleDOI
The phenomena of spin-filter tunnelling
TL;DR: The spin filtering phenomenon allows one to obtain highly spin-polarized charge carriers generated from nonmagnetic electrodes using magnetic tunnel barriers as mentioned in this paper, and the possibility of employing ferrites and other methods opens the potential for display of this phenomenon at room temperature, which can be expected to lead to huge progress in spin injection and detection in semiconductors.
