Indirect to direct band gap crossover in two-dimensional WS2(1-x)Se2x alloys
Cyrine Ernandes, Lama Khalil, Hela Almabrouk +12
In atomically thin transition metal dichalcogenide semiconductors, there is a crossover from indirect to direct bandgap as the thickness drops to one monolayer, which comes with a…
Phase Transition in a Memristive Suspended MoS2 Monolayer Probed by Opto- and Electro-Mechanics
Julien Chaste, Imen Hnid, Lama Khalil +8
Semiconducting monolayer of 2D material are able to concatenate multiple interesting properties into a single component. Here, by combining opto-mechanical and electronic measureme…
Nanomechanical strain concentration on a 2D nanobridge within a large suspended bilayer graphene for molecular mass detection
Julien Chaste, Amine Missaoui, Amina Saadani +4
The recent emergence of strain gradient engineering directly affects the nanomechanics, optoelectronics and thermal transport fields in 2D materials. More specifically, large suspe…
Evidence of Direct Electronic Band Gap in two-dimensional van der Waals Indium Selenide crystals
Hugo Henck, Debora Pierucci, Jihene Zribi +12
Metal mono-chalcogenide compounds offer a large variety of electronic properties depending on chemical composition, number of layers and stacking-order. Among them, the InSe has at…
Van der Waals epitaxy of two-dimensional single-layer h-BN on graphite by molecular beam epitaxy: Electronic properties and band structure
Debora Pierucci, Jihene Zribi, Hugo Henck +11
We report on the controlled growth of h-BN/graphite by means of molecular beam epitaxy (MBE). X-ray photoelectron spectroscopy (XPS) suggests an interface without any reaction or i…
Electronic band structure of Two-Dimensional WS2/Graphene van der Waals Heterostructures
Hugo Henck, Zeineb Ben Aziza, Debora Pierucci +13
Combining single-layer two-dimensional semiconducting transition metal dichalcogenides (TMDs) with graphene layer in van der Waals heterostructures offers an intriguing means of co…
