In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

open access: yesAdvanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

Ultra‐Sensitive Short‐Wave Infrared Organic Photodetectors Enabled by a π‐Conjugation Extended Proquinoid Electron Acceptor

open access: yesAdvanced Functional Materials, EarlyView.
A novel proquinoid‐type electron acceptor, TQC‐4Cl, with an ultra‐narrow bandgap of 1.01 eV and spectral response beyond 1200 nm enables organic SWIR photodetectors. The optimized devices show a high EQE of 13.66% and high specific detectivity over 1012 Jones at 1200 nm under −0.5 V reverse bias with outstanding thermal stability, highlighting their ...

Domain‐Wall‐Free Sliding Ferroelectricity in Fully Commensurate 3R Transition Metal Dichalcogenide Bilayers

open access: yesAdvanced Functional Materials, EarlyView.
It is reported that the ferroelectric switching behavior of rhombohedral (3R) phase transition metal dichalcogenide (TMD) bilayers strongly depends on their domain structures. Single‐domain TMDs (SD‐TMDs) with domain‐wall‐free structures exhibit robust and stable polarization switching, whereas poly‐domain TMDs (PD‐TMDs) with randomly distributed ...
