Free carrier induced ferroelectricity in layered perovskites
Shutong Li, Turan Birol
Doping ferroelectrics with carriers is often detrimental to polarization. This makes the design and discovery of metals that undergo a ferroelectric-like transition challenging. In…

Chemical bonding and Born charge in 1T-HfS
Sabine N. Neal, Shutong Li, Turan Birol +1
We combine infrared absorption and Raman scattering spectroscopies to explore the properties of the heavy transition metal dichalcogenide 1T-HfS. We employ the LO-TO splitting…
