Ge1-xSnx optical devices : growth and applications

, 2014
We will introduce our Ge1-xSnx epitaxial growth process and we will illustrate its material quality by the performance of photodetectors containing a Ge/Ge1-xSnx/Ge quantum well with fully strained Ge1-xSnx layers.

Exploring the Catalytic Activity of Ge(II) and Sn(II) Cationic Crown Ether Complexes: Hydrosilylation

Chemistry – A European Journal, EarlyView.
Easily synthesized [Ge([12]crown‐4)2][OTf]2 catalyzes the hydrosilylation of aldehydes to give reductively coupled ethers via a carbonyl‐activated reaction pathway. The mechanism proceeds through two distinct steps: hydrosilylation followed by etherification. The open coordination face of the active cationic Ge(II) catalyst facilitates the coordination

Ex-situ n-type heavy doping of Ge1-xSnx epilayers by surface Sb deposition and pulsed laser melting [PDF]

, 2022
Ge1-xSnx alloys have attracted considerable attention for their promising electrical and optical properties. One of the main challenges for their successful implementation in devices concerns the fabrication of n-type heavily doped surface layers.

Without Scratching the Surface: Depth Profiling Compositional Muon Analysis of Ancient Faience From Egypt and Sudan

Archaeometry, EarlyView.
ABSTRACT The specific depth‐profiling capabilities of the muonic x‐ray emission spectroscopy (μ‐XES) technique have proved to be effective for examination of the elemental distribution within ancient coins. This ‘layered’ analysis can also be applied to the examination of ancient faience, the production of which can result in distinct layers (glaze ...

Te with Band Convergence [PDF]

, 2018
The multivalence bands in GeTe provide an additional handle to manipulate the thermoelectric performance. Herein, the density‐functional‐theory calculation indicates that Cd doping enables the convergence of these multivalence bands. Plus, the additional

Chlorpyrifos modulates the mouse gut microbiota and metabolic activity

Environment International
The organophosphate chlorpyrifos is a commonly used pesticide for fruits and vegetables despite its association with neurotoxicity in humans. While some studies suggest that organophosphates may impact the gut microbiota, no studies to date have ...
