Conditions for domain-free negative capacitance
Prasanna Venkatesan Ravindran, Priyankka Gundlapudi Ravikumar, Asif Islam Khan
While negative capacitance has been demonstrated in ferroelectric-dielectric heterostructures in the form of capacitance enhancement, all experimental evidence, to date, suggests t…
Quantum phase transition in ferroelectric-paraelectric heterostructures
Prasanna Venkatesan Ravindran, Asif Islam Khan
Phase transition between ferroelectricity and quantum paraelectricity via non-thermal tuning parameters can lead to quantum critical behavior and associated emergent phenomena. Fer…
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…
Electrically Induced, Non-Volatile, Metal Insulator Transition in a Ferroelectric Gated MoS Transistor
Zhongyuan Lu, Claudy Serrao, Asif I. Khan +4
We demonstrate an electrically induced, non-volatile, metal-insulator phase transition in a MoS transistor. A single crystalline, epitaxially grown, PbZrTiO…
