Comparative Performance of MP2 and CCSD Methods in Predicting the Nanothermodynamics of Doped ZNO Clusters

This study demonstrates that while MP2 systematically overestimates vibrational frequencies and Zero-Point Vibrational Energy in doped ZnO nanoclusters compared to the more accurate CCSD method, both approaches reveal that entropic stabilization from dense low-frequency vibrational modes becomes dominant at temperatures exceeding 1000 K, thereby establishing a rigorous computational baseline for parameterizing DFT-D in future nanomaterial design.
