Gate-tunable diode and photovoltaic effect in an organic-2D layered material p-n junction
Saül Vélez, David Ciudad, Joshua Island +8
The semiconducting p-n junction is a simple device structure with great relevance for electronic and optoelectronic applications. The successful integration of low-dimensional mate…
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…
Precise and reversible band gap tuning in single-layer MoSe2 by uniaxial strain
Joshua O. Island, Agnieszka Kuc, Erik H. Diependaal +4
We present photoluminescence (PL) spectroscopy measurements of single-layer MoSe2 as a function of uniform uniaxial strain. A simple clamping and bending method is described that a…
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…
Titanium trisulfide (TiS3): a 2D semiconductor with quasi-1D optical and electronic properties
Joshua O. Island, Robert Biele, Mariam Barawi +7
We present characterizations of few-layer titanium trisulfide (TiS3) flakes which, due to their reduced in-plane structural symmetry, display strong anisotropy in their electrical…
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…
Photocurrent generation with two-dimensional van der Waals semiconductors
Michele Buscema, Joshua O. Island, Dirk J. Groenendijk +4
Two-dimensional (2D) materials have attracted a great deal of interest in recent years. This family of materials allows for the realization of versatile electronic devices and hold…
TiS3 transistors with tailored morphology and electrical properties
Joshua O. Island, Mariam Barawi, Robert Biele +9
Control over the morphology of TiS3 is demonstrated by synthesizing 1D nanoribbons and 2D nanosheets. The nanosheets can be exfoliated down to a single layer. Through extensive cha…
Pick-up and drop transfer of diamond nanosheets
V. Seshan, J. O. Island, R. van Leeuwen +9
Nanocrystalline diamond (NCD) is a promising material for electronic and mechanical micro- and nanodevices. Here we introduce a versatile pick-up and drop technique that makes it p…
Tailoring 10 nm Scale Suspended Graphene Junctions and Quantum Dots
V. Tayari, A. C. McRae, S. Yigen +3
The possibility to make 10 nm scale, and low-disorder, suspended graphene devices would open up many possibilities to study and make use of strongly coupled quantum electronics, qu…
Mechanical manipulation and exfoliation of boron nitride flakes by micro-plowing with an AFM tip
Joshua O. Island, Gary A. Steele, Herre S. J. can der Zant +1
We demonstrate a simple method to manipulate and exfoliate thick hexagonal boron nitride (h-BN) flakes using an atomic force microscope (AFM) cantilever and tip mounted to a microm…
