DOI: 10.1103/physrevapplied.12.034027

Abstract: Materials featuring negative thermal expansion (NTE) attract attention due to their numerous applications in printed circuit boards, machinery, optical-fiber reflective grating devices, and high-precision mirrors. Unfortunately, most large samples of NTE material are very sensitive… read more here.

DOI: 10.1103/physrevmaterials.3.024401

Abstract: The interest in ferroelectric van der Waals crystals arises from the potential to realize ultrathin ferroic systems owing to the reduced surface energy of these materials and the layered structure that allows for exfoliation. Here,… read more here.
