Photo-induced currents and short-term memory for reservoir computing in a ferroelectric semiconductor
Yan Meng Chong, Atreya Majumdar, Manuel Zahn +3
Physical reservoir computing represents an energy efficient approach for processing temporal signals by exploiting the intrinsic nonlinear dynamics and fading memory of a physical…
The domain-wall/metal-electrode injection barrier in lithium niobate: Which electrical transport model fits best?
Manuel Zahn, Elke Beyreuther, Iuliia Kiseleva +3
The comprehensive description of both the electrical transport along conductive domain walls (CDWs) in lithium niobate (LNO) single crystals and the charge injection at the interfa…
Domain-wall driven suppression of thermal conductivity in a ferroelectric polycrystal
Rachid Belrhiti-Nejjar, Manuel Zahn, Patrice Limelette +8
A common strategy for reducing thermal conductivity of polycrystalline systems is to increase the number of grain boundaries. Indeed, grain boundaries enhance the probability of ph…
Reversible long-range domain wall motion in an improper ferroelectric
M. Zahn, A. M. Müller, K. P. Kelley +8
Reversible ferroelectric domain wall movements beyond the 10 nm range associated with Rayleigh behavior are usually restricted to specific defect-engineered systems. Here, we demon…
Towards the reproducible fabrication of conductive ferroelectric domain walls into lithium niobate bulk single crystals
Julius Ratzenberger, Iuliia Kiseleva, Boris Koppitz +7
Ferroelectric domain walls (DWs) are promising structures for assembling future nano-electronic circuit elements on a larger scale, since reporting domain wall currents of up to 1…
