Probing the Architecture of Organic Heterojunctions Based on Zn(Salen)‐Type/Lu(Bis‐phthalocyanine) Complexes and Their Potential Application as Gas Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
Planar bilayer heterojunctions are fabricated from two molecular materials and compared to solution‐processed bulk heterojunctions. Raman spectroscopy and conductive AFM studies reveal the formation of conductive pillar‐like structures within a poorly conductive matrix.

Thermal Enhancement of TADF‐OLED Performance: Size of Active Area Matters

open access: yesAdvanced Materials Interfaces, EarlyView.
Large‐area TADF‐based OLEDs can be used as thermally assisted light‐emitting devices, in which moderate waste heat can partially compensate for efficiency losses associated with increasing active area. ABSTRACT Temperature significantly impacts the performance of light‐emitting diodes, typically causing degradation as they heat up. However, OLEDs using

Deep Eutectic Solvent‐Enhanced PEDOT: PSS/NR Foam Piezoresistive Sensor for High‐Sensitivity Wearable Devices and Sleep Monitoring Applications

open access: yesAdvanced Materials Interfaces, EarlyView.
A high‐performance piezoresistive foam sensor is developed by integrating natural rubber, PEDOT: PSS, and a deep eutectic solvent (DES). DES effectively detaches insulating PSS from PEDOT, dramatically amplifying electrical conductivity and sensitivity.

Band Alignment of Grafted Si/Ge0.89Sn0.11 Heterojunction Determined by X‐Ray Photoelectron Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT We investigate the band alignment of a monocrystalline grafted p‐type Si/Ge0.89Sn0.11 heterostructure using X‐ray photoelectron spectroscopy (XPS). The bandgap of the Ge0.89Sn0.11 epilayer of 0.50 eV was first determined and cross‐verified using photoluminescence spectroscopy, infrared transmission, and theoretical calculation.
