X-ray photoemission study of CoFeB/MgO thin film bi-layers
J. C. Read, P. G. Mather, R. A. Buhrman
We present results from an X-ray photoemission spectroscopy (XPS) study of CoFeB/MgO bi-layers where we observe process-dependent formation of B, Fe, and Co oxides at the CoFeB/MgO…
Disorder, defects and bandgaps in ultra thin (001) MgO tunnel barrier layers
P. G. Mather, J. C. Read, R. A. Buhrman
We report scanning tunneling spectroscopy studies of the electronic structure of 1.5 to 3 nm (001) textured MgO layers grown on (001) Fe. Thick MgO layers exhibit a bulk-like band…
Tunneling spectroscopy studies of aluminum oxide tunnel barrier layers
P. G. Mather, A. C. Perrella, E. Tan +2
We report scanning tunneling microscopy and ballistic electron emission microscopy studies of the electronic states of the uncovered and chemisorbed-oxygen covered surface of AlOx…
Oxygen stoichiometry and instability in aluminium oxide tunnel barrier layers
E. Tan, P. G. Mather, A. C. Perrella +2
We present X-ray photoelectron spectroscopy data which show that the chemisorbed oxygen previously observed to be on the surface of thin AlOx layers formed by room temperature ther…
