Clarification of the Spontaneous Polarization Direction in Crystals with Wurtzite Structure
Simon Fichtner, Mohamed Yassine, Chris van de Walle +1
The wurtzite structure is one of the most frequently found crystal structures in modern semiconductors and its inherent spontaneous polarization is a defining materials property. D…
Wafer scale reactive sputtering of highly oriented and ferroelectric AlScN from 300 mm AlSc Targets
Tom-Niklas Kreutzer, Muhammad Zubair Ghori, Md Redwanul Islam +4
This paper presents progress towards the large-scale manufacturability of piezo- and ferroelectric AlScN thin films with very high Sc content. AlScN lay…
Advancing Measurement Capabilities in Lithium-Ion Batteries: Exploring the Potential of Fiber Optic Sensors for Thermal Monitoring of Battery Cells
Florian Krause, Felix Schweizer, Alexandra Burger +5
This work demonstrates the potential of fiber optic sensors for measuring thermal effects in lithium-ion batteries, using a fiber optic measurement method of Optical Frequency Doma…
Demonstration and STEM Analysis of Ferroelectric Switching in MOCVD-Grown Single Crystalline AlScN
Niklas Wolff, Georg Schoenweger, Isabel Streicher +10
Wurtzite-type AlScN solid solutions grown by metal organic chemical vapour deposition are for the first time confirmed to be ferroelectric. The film with 230 nm thickne…
Ultrathin AlScN for low-voltage driven ferroelectric-based devices
Georg Schönweger, Md Redwanul Islam, Niklas Wolff +4
Thickness scaling of ferroelectricity in AlScN is a determining factor for its potential application in neuromorphic computing and memory devices. In this letter, we report on ultr…
On the exceptional temperature stability of ferroelectric AlScN thin films
MD Redwanul Islam, Niklas Wolff, Mohammed Yassine +7
Through its dependence on low symmetry crystal phases, ferroelectricity is inherently a property tied to the lower temperature ranges of the phase diagram for a given material. Thi…
An Approach to State Signal Shaping by Limit Cycle Model Predictive Control
Carlos Cateriano Yáñez, Gerwald Lichtenberg, Georg Pangalos +1
A novel nonlinear model predictive control approach for state signal shaping is proposed. The control strategy introduces a residual shape cost kernel based on the dynamics of circ…
AlScN: A III-V semiconductor based ferroelectric
Simon Fichtner, Niklas Wolff, Fabian Lofink +2
Ferroelectric switching is unambigiously demonstrated for the first time in a III-V semiconductor based material: AlScN -- A discovery which could help to satisfy the urgent demand…
Rank-constrained fundamental matrix estimation by polynomial global optimization versus the eight-point algorithm
Florian Bugarin, Adrien Bartoli, Didier Henrion +3
The fundamental matrix can be estimated from point matches. The current gold standard is to bootstrap the eight-point algorithm and two-view projective bundle adjustment. The eight…
