Fast Yet Quantum-Efficient Few-Layer Vertical MoS2 Photodetectors
David Maeso, Andres Castellanos-Gomez, Nicolas Agraït +1
Semiconducting 2D materials, such as molybdenum disulfide (MoS2) and other members of the transition metal dichalcogenide family, have emerged as promising materials for applicatio…
Strong Modulation of Optical Properties in Rippled 2D GaSe via Strain Engineering
David Maeso, Sahar Pakdel, Hernan Santos +4
Few-layer GaSe is one of the latest additions to the family of 2D semiconducting crystals whose properties under strain are still relatively unexplored. Here, we study rippled nano…
Photodiodes based in La0.7Sr0.3MnO3/single layer MoS2 hybrid vertical heterostructures
Yue Niu, Riccardo Frisenda, Simon A. Svatek +9
The fabrication of artificial materials by stacking of individual two-dimensional (2D) materials is amongst one of the most promising research avenues in the field of 2D materials.…
High current density electrical breakdown of TiS3 nanoribbon-based field-effect transistors
Aday J. Molina-Mendoza, Joshua O. Island, Wendel S. Paz +11
The high field transport characteristics of nanostructured transistors based on layered materials are not only important from a device physics perspective but also for possible app…
Gate Tunable Photovoltaic Effect in MoS2 vertical P-N Homostructures
Simon A. Svatek, Elisa Antolin, Der-Yuh Lin +8
P-n junctions based on vertically stacked single or few layer transition metal dichalcogenides (TMDCs) have attracted substantial scientific interest. Due to the propensity of TMDC…
Strong quantum confinement effect in the optical properties of ultrathin α-In2Se3
Jorge Quereda, Robert Biele, Gabino Rubio-Bollinger +3
The effect of quantum confinement in the optical absorption spectra of atomically thin α-In2Se3 crystals is studied, observing a huge thickness-dependent shift in the optical band…
