title = "Isotropic negative area compressibility over large pressure range in potassium beryllium fluoroborate and its potential applications in deep ultraviolet region",
abstract = "The very rare isotropic negative area compressibility is observed in KBBF and the related mechanism is investigated by combined high-pressure X-Ray Diffraction (XRD) experiments and first-principles calculations. The strong mechanical anisotropy leads to large Poisson's ratio and high figure of merit for acoustic-optics effect, giving KBBF potential applications as smart strain converters and deep-ultraviolet (DUV) acoustic-optic devices.
