Gate controlled photocurrent generation mechanisms in high-gain In2Se3 phototransistors
Joshua O. Island, Sofya I. Blanter, Michele Buscema +2
Photocurrent in photodetectors incorporating van der Waals materials is typically produced by a combination of photocurrent generation mechanisms that occur simultaneously during o…
Centimeter-scale synthesis of ultrathin layered MoO3 by van der Waals epitaxy
Aday J. Molina-Mendoza, Jose Luis Lado, Joshua Island +12
We report on the large-scale synthesis of highly oriented ultrathin MoO3 layers using a simple and low-cost atmospheric pressure by van der Waals epitaxy growth on muscovite mica s…
Image effects in transport at metal-molecule interfaces
C. J. O. Verzijl, J. A. Celis Gil, M. L. Perrin +3
We present a method for incorporating image-charge effects into the description of charge transport through molecular devices. A simple model allows us to calculate the adjustment…
Temperature dependent Raman spectroscopy of titanium trisulfide (TiS3) nanoribbons and nanosheets
Amit S. Pawbake, Joshua O. Island, Eduardo Flores +7
Titanium trisulfide (TiS3) has recently attracted the interest of the 2D community as it presents a direct bandgap of ~1.0 eV, shows remarkable photoresponse, and has a predicted c…
Control of biaxial strain in single-layer Molybdenite using local thermal expansion of the substrate
G. Plechinger, A. Castellanos-Gomez, M. Buscema +6
Single-layer MoS2 is a direct-gap semiconductor whose electronic band structure strongly depends on the strain applied to its crystal lattice. While uniaxial strain can be easily a…
Superconducting molybdenum-rhenium electrodes for single-molecule transport studies
R. Gaudenzi, J. O. Island, J. de Bruijckere +3
We demonstrate that electronic transport through single molecules or molecular ensembles, commonly based on gold (Au) electrodes, can be extended to superconducting electrodes by c…
Fabrication of hybrid molecular devices using multi-layer graphene break junctions
Joshua O. Island, Anastasia Holovchenko, Max Koole +5
We report on the fabrication of hybrid molecular devices employing multilayer graphene (MLG) flakes which are patterned with a constriction using a helium ion microscope (HIM) or a…
