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

open access: yesAdvanced 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 ...

From Spirocyclic Germanium Alkoxides to their Fluorido Germanates

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 18, June 24, 2025.
Spirocyclic germanium salicyl alcoholates potentially meet the requirement as molecular precursors for twin polymerization, which is defined as a concerted formation of two polymeric materials from a so‐called twin monomer. Two examples of such germanium alkoxides and their associated fluorido germanates are reported and aspects of their chirality and ...

Efficient In Situ Doping of Strained Germanium Tin Epilayers at Unusually Low Temperature

open access: yesAdvanced Electronic Materials, Volume 10, Issue 9, September 2024.
Efficient p‐ and n‐type in situ doping of compressively strained germanium tin (Ge1‐xSnx) semiconductor epilayers, grown by chemical vapor deposition on a standard Si(001) substrate, is demonstrated. Materials characterization results reveal unusual impact of dopants manifesting via a pronounced reduction of Sn content in the epilayer, accompanied by ...
