- •
Increased medium range order in amorphous Ta2O5 has been observed due to increased temperature thermal annealing.
- •
Virtual Dark-Field Imaging has been employed to spatially resolve the medium range order.
- •
We propose a tentative model for the mechanism underlying the correlation between medium range order and internal friction.
