Investigating and controlling charge carrier behavior in p-type delafossite CuFeO₂ photocathodes for solar fuel production

Mathieu Steven Prévot

Humanity is facing the challenge of a global-scale energy transition over the next decades, where solar energy is set to play a crucial role. With the immense amount of sunlight reaching the surface or the Earth, and constantly decreasing manufacturing cos ...

Electron and Hole Mobilities in Single-Layer WSe2

Andras Kis, Adrien Victor Allain

Single-layer transition metal dichalcogenide WSe2 has recently attracted a lot of attention because it is a 2D semiconductor with a direct band gap. Due to low doping levels, it is intrinsic and shows ambipolar transport. This opens up the possibility to r ...
