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…
