A Novel Analysis Framework for Microstructural Characterization of Ferroelectric Hafnia: Experimental Validation and Application
Herein, we present a novel analysis framework for grain size profile of ferroelectric hafnia to tackle critical shortcomings inherent in the current microstructural analysis. We vastly enhanced visibility of grains with ion beam treatment and performed accurate grain segmentation using deep neural network (DNN). By leveraging our new method, we discovered unexpected discrepancies that contradict previous results, such as deposition temperature (Tdep) and post-metallization annealing (PMA) depen…

Das BSI warnt: Immer weniger Menschen nutzen 2FA und sichere Passwörter, obwohl Cybergefahren steigen. Nur 34% setzen auf 2FA, Updates werden vernachlässigt, Firewalls sind out. Die Argumentation des BSI ist klar: Wer sich schützt, bleibt seltener Opfer. Doch die Bereitschaft (und Unkenntnis) sinkt – fatal! #Cybersecurity

2024 waren wir mit der Schachtour auf dem Schulfest des Wilhelmsgymnasiums in Stuttgart-Degerloch. Dort haben wir neben den Feierlichkeiten auch etwas Schach angeboten und unser Maskottchen Chessy war natürlich auch mit am Start.
Falls ihr aus dem Osten kommt und Lust habt, dass wir diesen Sommer zu euch kommen, meldet euch gerne hier an:

Universally enhanced superconductivity and coexisting ferroelectricity at oxide interfaces
The coexistence of superconductivity and ferroelectricity is rare due to their conflicting requirements: superconductivity relies on free charge carriers, whereas ferroelectricity typically occurs in insulating systems. At LaAlO3/KTaO3 interfaces, we demonstrate the coexistence of two-dimensional superconductivity and ferroelectricity, enabled by the unique properties of KTaO3 as a quantum paraelectric. Systematic gating and poling experiments reveal a universal enhancement of the superconducti…

Challenges and opportunities in piezoelectric polymers: Effect of oriented amorphous fraction in ferroelectric semicrystalline polymers
Despite extensive research on piezoelectric polymers since the discovery of piezoelectric poly(vinylidene fluoride) (PVDF) in 1969, the fundamental physics of polymer piezoelectricity has remained elusive. Based on the classic principle of piezoelectricity, polymer piezoelectricity should originate from the polar crystalline phase. Surprisingly, the crystal contribution to the piezoelectric strain coefficient d31 is determined to be less than 10%, primarily owing to the difficulty in changing t…
