Integration of Refractive Microlenses on BP/MoS2 Photodiodes for Enhanced Infrared Photodetection

Small, EarlyView.
This study demonstrates the successful integration of black phosphorus/molybdenum disulfide infrared photodetectors with refractive microlenses to significantly enhance detection. The design achieves a 20‐fold photocurrent enhancement, enabling a room‐temperature detectivity of 1.83 × 109 cmHz1/2W−1, and demonstrates high‐resolution (1023 × 768) single‐

Nanoscopic Observation of Structural Changes After First‐Firing Behavior in W/GeTe/W Ovonic Threshold Switches Using AFM Tip–Based Local Biasing

Small Methods, EarlyView.
A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.

Unveiling Ca9N4Te3: A New Motif in Alkaline‐Earth Metal Chalcogenide Nitrides: A Combined Experimental and Computational Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The unique double monocapped trigonal cupola coordination polyhedra of Te(2) atoms inside the crystal structure of Ca9N4Te3. Green, moisture‐sensitive Ca9N4Te3 was obtained from Ca/Na flux at 1173 K as a by‐product of reddish‐brown Ca6N2Te3 and crystallizes in the trigonal space group R3¯$\overline{3}$ (No. 148, Z = 3).

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.
