High Throughput Characterization of Epitaxially Grown Single-Layer MoS2
Foad Ghasemi, Riccardo Frisenda, Dumitru Dumcenco +3
The growth of single-layer MoS2 with chemical vapor deposition is an established method that can produce large-area and high quality samples. In this article, we investigate the ge…
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…
Micro-reflectance and transmittance spectroscopy: a versatile and powerful tool to characterize 2D materials
Riccardo Frisenda, Yue Niu, Patricia Gant +9
Optical spectroscopy techniques such as differential reflectance and transmittance have proven to be very powerful techniques to study 2D materials. However, a thorough description…
Highly responsive UV-photodetectors based on single electrospun TiO2 nanofibres
Aday J. Molina-Mendoza, Alicia Moya, Riccardo Frisenda +9
In this work we study the optoelectronic properties of individual TiO2 fibres produced through coupled sol-gel and electrospinning, by depositing them onto pre-patterned Ti/Au elec…
Enhanced Visibility of MoS2, MoSe2, WSe2 and Black Phosphorus: Making Optical Identification of 2D Semiconductors Easier
Gabino Rubio-Bollinger, Ruben Guerrero, David Perez de Lara +5
We explore the use of Si3N4/Si substrates as a substitute of the standard SiO2/Si substrates employed nowadays to fabricate nanodevices based on 2D materials. We systematically stu…
Transverse ratchet effect and superconducting vortices: Simulation and experiment
L. Dinis, D. Perez de Lara, E. M. Gonzalez +3
A transverse ratchet effect has been measured in magnetic/superconducting hybrid films fabricated by electron beam lithography and magnetron sputtering techniques. The samples are…
Vortex ratchet reversal: The role of interstitial vortices
D. Perez de Lara, M. Erekhinsky, E. M. Gonzalez +3
Triangular arrays of Ni nanotriangles embedded in superconducting Nb films exhibit unexpected dynamical vortex effects. Collective pinning with a vortex lattice configuration diffe…
Control of the chirality and polarity of magnetic vortices in triangular nanodots
M. Jaafar, R. Yanes, D. Perez de Lara +6
Magnetic vortex dynamics in lithographically prepared nanodots is currently a subject of intensive research, particularly after recent demonstration that the vortex polarity can be…
Rocking ratchet induced by pure magnetic potentials with broken reflection symmetry
D. Perez de Lara, F. J. Castano, B. G. Ng +7
A ratchet effect (the rectification of an ac injected current) which is purely magnetic in origin has been observed in a superconducting-magnetic nanostructure hybrid. The hybrid c…
