Coexistence of polar and antipolar phases in ferroelectric halide perovskite CsGeBr
Ravi Kashikar, S. Lisenkov, I. Ponomareva
Recently ferroelectricity has been demonstrated in the family of halide perovskites: CsGeX (X=Cl, Br, I). We develop a first-principles-based computational approach to probe fi…
First-Principles Property Assessment of Hybrid Formate Perovskites
Abduljelili Popoola, Partha Sarathi Ghosh, Maggie Kingsland +7
Hybrid organic inorganic formate perovskites, AB(HCOO), is a large family of compounds which exhibit variety of phase transitions and diverse properties. Some examples include…
Enhanced piezoelectric response at nanoscale vortex structures in ferroelectrics
Xiaowen Shi, Nimish Prashant Nazirkar, Ravi Kashikar +13
The piezoelectric response is a measure of the sensitivity of a material's polarization to stress or its strain to an applied field. Using in-operando x-ray Bragg coherent diffract…
