🥳 Congrats to Ragini Gupta and Sebastian Lukas on their new paper! We integrated PtSe₂ piezoresistive pressure sensors into a Wheatstone bridge, cutting illumination-induced drift to near zero and repeatability error by 7x.

Drift Reduction in 2D PtSe<sub>2</sub> Piezoresistive Pressure Sensors Through an On‐Chip Wheatstone Bridge

Drift is a major source of error affecting the accuracy and repeatability of sensors. A Wheatstone bridge (WSB) enables high sensitivity, accuracy, and the elimination of common-mode drift. We apply ...

New in Nature Materials: we mapped leakage current across hBN, MoS₂, and WS₂ vs. industrial SiO₂. Monolayer #hBN leaks more than monolayer #MoS₂ & #WS₂ despite 3x larger bandgap, because it's ~50% thinner. Key reliability data for 2D devices. doi.org/10.1038/s415... #2DMaterials #Nanoelectronics

Quantum tunnelling and leakage current across two-dimensional materials - Nature Materials

Leakage current affects the operation and reliability of electronic devices, but obtaining accurate measurements of leakage current across two-dimensional (2D) materials has been difficult. This artic...

Aachen meets Berlin — Strengthening Europe’s High‑Tech Future Aachen delegation holds fruitful discussions about AI and #semiconductor technologies with representatives of the German Parliament and federal ministries. I am encouraged by the willingness to move ahead, politically and technologically.
