Article summary:
1. The electronic and negative thermal expansion (NTE) properties of Zn3[Fe(CN)6]2 have been studied using first-principles calculation.
2. The NTE behavior is closely associated with transverse vibration in the same direction of bridge atoms (C and N atoms).
3. Low-frequency phonons play a significant role in the NTE behavior, with acoustic phonons having the most negative mode/total Grüneisen parameter.
Article analysis:
The article “The negative thermal expansion behavior in Prussian blue analogue Zn3[Fe(CN)6]2: A first-principles study” is a well-written and comprehensive piece of research that provides an in-depth analysis of the electronic and thermal expansion properties of Zn3[Fe(CN)6]2. The authors have used first-principles calculations to demonstrate the NTE behavior, which is closely associated with transverse vibration in the same direction of bridge atoms (C and N atoms). Furthermore, they have identified low-frequency phonons as playing a significant role in this process, with acoustic phonons having the most negative mode/total Grüneisen parameter.
