Atomic short-range order: a new degree of freedom for band engineering of GeSn semiconductor alloys

Shang Liu, Yunfan Liang, Nirosh M. Eldose +18

Chemical short-range order (SRO) in alloys denotes the statistical preference or avoidance between atomic species on neighboring lattice sites. Here, we highlight SRO as a powerful…

Local Alloy Order in a Ge1-xSnx/Ge Epitaxial Layer

Agnieszka Anna Corley-Wiciak, Shunda Chen, Omar Concepción +6

The local ordering of atoms in alloys directly has a strong impact on their electronic and optical properties. This is particularly relevant in nonrandom alloys, especially if they…

Engineering tunable strain fields in suspended graphene by microelectromechanical systems

Jens Sonntag, Matthias Goldsche, Tymofiy Khodkov +5

Here, we present a micro-electromechanical system (MEMS) for the investigation of the electromechanical coupling in graphene and potentially related 2D materials. Key innovations o…

Lasing in Group-IV materials

V. Reboud, D. Buca, H. Sigg +6

Silicon photonics in the near-Infra-Red, up to 1.6 um, is already one of key technologies in optical data communications, particularly short-range. It is also being prospected for…

Design of a waveguide-coupled GeSn disk laser

Bahareh Marzban, Jovana Nojic, Daniela Stange +2

We report on the design of a waveguide coupled GeSn microdisk-laser cavity in which the germanium virtual substrate serving as a template for GeSn growth is repurposed for the defi…
