Abstract

The tunnel momentum distribution in a magnetic tunnel junction is probed by analyzing the decayof the hot electrons in the Co metal anode after tunneling, using a three-terminal transistor structurein which the hot-electron attenuation is sensitive to the tunnel momentum distribution. Solid stateamorphous Al₂O₃ barriers and the vacuum barrier of a scanning tunneling microscope arecompared. For the former the attenuation length in nominally the same Co is strikingly larger factorof 2, implying a more isotropic tunnel momentum distribution for Al₂O₃ barriers.
