Vertical Phase Separation in Blended Organic Semiconducting Films and Impact on Their Electrical and Direct X‐Ray Detection Properties

open access: yesAdvanced Electronic Materials, EarlyView.
The composition of blends of 1,4,8,11‐tetramethyl‐6,13‐triethylsilylethynyl pentacene (TMTES) and polystyrene (PS) to be used in Organic Field‐Effect Transistors (OFETs) is optimized to achieve and enhance thin film crystallinity and a reduced charge trap density at the semiconductor/dielectric interface.

Low‐boiling Point Perfluorocarbon Nanodroplets as Dual‐Phase Dual‐Modality MR/US Contrast Agent

open access: yesChemPhysChem, Volume 23, Issue 24, December 16, 2022., 2022
Low‐boiling point perfluorocarbon nanodroplets is vaporized into microbubbles using acoustic activation, establishing them as phase‐change contrast agents for ultrasound. The unique hyperCEST signatures of nanodroplets and microbubbles are demonstrated, enabling their use not only as a dual‐phase but also as a dual‐modality MR/US contrast agent ...

A Review of Ga₂O₃ Heterojunctions for Deep‐UV Photodetection: Current Progress, Methodologies, and Challenges

open access: yesAdvanced Electronic Materials, EarlyView.
This paper provides a comprehensive review of the existing literature related to the fundamentals of gallium oxide (Ga2O3), growth methods, substrates, and particularly a focused examination of Ga2O3‐based heterojunctions. Particular attention has also been given to the state‐of‐the‐art Ga2O3‐based heterojunctions for photodetectors. The key challenges

Magnetic Precursor to the Structural Phase Transition in V2O3

open access: yesAdvanced Electronic Materials, EarlyView.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

Correlation of Band Bending and Ionic Losses in 1.68 eV Wide Band Gap Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Piperazinium salt treatments with different anions (chloride, iodide, tosylate, and bistriflimide) influence the energetics, carrier dynamics and long‐term stability of 1.68 eV perovskite solar cells. Chloride treatments achieve the highest efficiency (21.5%) but suffer from fast degradation due to ionic losses.
