Antiferroelectric negative capacitance from a structural phase transition in zirconia
Michael Hoffmann, Zheng Wang, Nujhat Tasneem +20
Crystalline materials with broken inversion symmetry can exhibit a spontaneous electric polarization, which originates from a microscopic electric dipole moment. Long-range polar o…
Ferroelectric Negative Capacitance Domain Dynamics
Michael Hoffmann, Asif Islam Khan, Claudy Serrao +6
Transient negative capacitance effects in epitaxial ferroelectric Pb(ZrTi)O capacitors are investigated with a focus on the dynamical switching behavior governe…
Differential voltage amplification from ferroelectric negative capacitance
Asif I. Khan, Michael Hoffmann, Korok Chatterjee +8
It is well known that one needs an external source of energy to provide voltage amplification. Because of this, conventional circuit elements such as resistors, inductors or capaci…
A computational study of hafnia-based ferroelectric memories: from ab initio via physical modeling to circuit models of ferroelectric device
Milan Pešić, Christopher Künneth, Michael Hoffmann +7
The discovery of ferroelectric properties of binary oxides revitalized the interest in ferroelectrics and bridged the scaling gap between the state-of-the-art semiconductor technol…
