Effect of Electromigration on Grooving:

Setup 1: CVD-CCT Experiments

This asymmetry shows further enhancement upon any increase in the electron wind intensity parameter .

The constant voltage condition up to 95% reduction in the cathode contact area; cause a steady decrease in the net current flow through the cathode contact area, showing almost inverse exponential type shrinkage with the normalized time.


This application manifests itself in the electrostatic potential vs. arclength graphs with a drastic decrease on the onset of cathode detachment. Fig. 6.
