- We present current versus voltage (I-V) measurement on superconducting Nb films with diluted triangular arrays (honeycomb and kagome) of antidots. Peaks and dips appearing in the derivative (dV/dI) of I-V curves showing the variation in the resistance is the indication of Josephson Junctions like weak-links in these systems. These observations also reveal the presence of mobile interstitial vortices in these lattices with regular pinning arrays. This behavior is predominant in honeycomb arrays due to large density of interstitial spaces in this system as compared that of to kagome lattice. This behavior can be tuned by temperature as well as external magnetic field but the tuning values of these parameters can be different for different symmetries of antidots.
