… A recent paper in Science made the claim of 92% polarization for the injection spin polarized electrons … tip into GaAs(110). Actually they state their result as 92% efficiency for the injection of 100% importance for the … imply that the actual polarization was much less than 92%. Since the tip is not 100% spin polarized, it makes no …
