PROJECT TITLE :

Study on Cu/Ni Nano Superlattice Conductors for Reduced RF Loss

ABSTRACT:

We have a tendency to report on Cu/Ni paired superlattice conductors featuring reduced radio frequency (RF) loss primarily based on eddy current cancelling (ECC). Conjointly, the results of the width and the individual layer thickness of the superlattice conductors are studied for improved RF performance. The usage of Ni as the ferromagnetic material within the non-ferromagnetic/ferromagnetic superlattice structure is advantageous as it's a high contrast between the in-plane and out-of-plane magnetic coercivity fields making it appropriate for effective skinny film superlattice ECC, is abundant, and will not require a stoichiometric control of composition as other alloy magnetic materials do. Ni's negative permeability is additionally in a position to effectively cancel out the positive permeability of copper in the frequency of interest. A transmission line consisting of 10 superlattice Cu/Ni layers, with each layer being of a hundred and fifty nm/25 nm totaling 1.seventy five shows the same resistance value joined consisting of ten Cu/Ni layers with each being 60zero nm/one hundred nm totaling 7 thick at thirteen GHz, revealing seventy fivepercent conductor volume reduction. Experimental results show a lot of than three times improvement in the figure of benefit defined as frequency/effective resistivity, compared with alternative state-of-the-art devices.
