Relevance of Ge incorporation to control the physical behaviour of point defects in kesterite
Thomas Ratz, Ngoc Duy Nguyen, Guy Brammertz +2
To reduce the prominent VOC-deficit that limits kesterite-based solar cells efficiencies, Ge has been proposed over the recent years with encouraging results, as the reduction of t…
Opto-electronic properties and solar cell efficiency modelling of CuZnXS (X=Sn,Ge,Si) kesterites
Thomas Ratz, Jean-Yves Raty, Guy Brammertz +2
In this work, first principle calculations of CuZnSnS (CZTS), CuZnGeS (CZGS) and CuZnSiS (CZSS) are performed to highlight the impact of the cationic substi…
A roadmap for the design of four-terminal spin valves and the extraction of spin diffusion length
Emile Fourneau, Alejandro V. Silhanek, Ngoc D. Nguyen
Graphene is a promising substrate for future spintronics devices owing to its remarkable electronic mobility and low spin-orbit coupling. Hanle precession in spin valve devices is…
On the origin of the giant spin detection efficiency in tunnel barrier based electrical spin detector
Emile Fourneau, Alejandro V. Silhanek, Ngoc Duy Nguyen
Efficient conversion of a spin signal into an electric voltage in mainstream semiconductors is one of the grand challenges of spintronics. This process is commonly achieved via a f…
Trapping of electrons around nanoscale metallic wires embedded in a semiconductor medium
Chi Cuong Huynh, R. Evrard, Ngoc Duy Nguyen
We predict that conduction electrons in a semiconductor film containing a centered square array of metal nanowires normal to its plane are bound in quantum states around the centra…
