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…
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…
Negative Capacitance in a Ferroelectric Capacitor
Asif Islam Khan, Korok Chatterjee, Brian Wang +6
The Boltzmann distribution of electrons poses a fundamental barrier to lowering energy dissipation in conventional electronics, often termed as Boltzmann Tyranny. Negative capacita…
Experimental Evidence of Ferroelectric Negative Capacitance in Nanoscale Heterostructures
Asif Islam Khan, Debanjan Bhowmik, Pu Yu +4
We report a proof-of-concept demonstration of negative capacitance effect in a nanoscale ferroelectric-dielectric heterostructure. In a bilayer of ferroelectric, Pb(Zr0.2Ti0.8)O3 a…
