High Mobility and Electrostatics in GeSn Quantum Wells With SiGeSn Barriers

Advanced Electronic Materials, Volume 11, Issue 19, November 18, 2025.
This study investigates electrical transport in GeSn quantum wells with SiGeSn barriers and characterizes hole mobilities as a function of hole density. The observed mobilities are higher than previously reported for GeSn quantum wells with similar compositions but with a Ge barrier.

Personalized mixture toxicity testing: A proof-of-principle in vitro study evaluating the steroidogenic effects of reconstructed contaminant mixtures measured in blood of individual adults

Environment International
Chemical risk assessments typically focus on single substances, often overlooking real-world co-exposures to chemical mixtures. Mixture toxicology studies using representative mixtures can reveal potential chemical interactions, but these do not account ...

Extremely High Electron Mobility in GeSn Epitaxial Films by Chemical Vapor Deposition

Advanced Electronic Materials, Volume 11, Issue 11, July 2025.
Transport properties in n‐GeSn films are investigated. By applying tensile stress or increasing the Sn fraction, electron mobility is significantly enhanced since more electrons populate the Γ‐valley, where the electron effective mass is small. A remarkably high electron Hall mobility of 6,200 cm2V−1s−1 is achieved in the strained‐relaxed n‐Ge0.88Sn0 ...
