Ex-situ Tunnel Junction Process Technique Characterized by Coulomb Blockade Thermometry [PDF]

open access: yes, 2010
We investigate a wafer scale tunnel junction fabrication method, where a plasma etched via through a dielectric layer covering bottom Al electrode defines the tunnel junction area. The ex-situ tunnel barrier is formed by oxidation of the bottom electrode

Study on the Influence of Train Dynamic Load on underneath Tunnel Cast-in-Situ Concrete in Early Age

open access: yesShock and Vibration, 2022
The cast-in-situ concrete lining is prone to structural damage, cracks, and other defects, due to the influence of dynamic load at an early age, which is necessary to study the dynamic response.

Sign of tunnel spin polarization of low-work-function Gd/Co nanolayers in a magnetic tunnel junction [PDF]

open access: yes, 2008
Magnetic tunnel junctions having a low-work-function Gd/Co nanolayer at the interface with an Al2O3 tunnel barrier are shown to exhibit both positive and negative values of the tunnel magnetoresistance. The sign of the tunnel spin polarization of the Gd/
