Photovoltaic and photothermoelectric effect in a double-gated WSe2 device
Dirk J. Groenendijk, Michele Buscema, Gary A. Steele +4
Tungsten diselenide (WSe2), a semiconducting transition metal dichalcogenide (TMDC), shows great potential as active material in optoelectronic devices due to its ambipolarity and…
Photovoltaic effect in few-layer black phosphorus PN junctions defined by local electrostatic gating
Michele Buscema, Dirk J. Groenendijk, Gary A. Steele +2
The photovoltaic effect is one of the fundamental light-matter interactions in light energy harvesting. In conventional photovoltaic solar cells, the photogenerated charge carriers…
Ultrahigh photoresponse of few-layer TiS3 nanoribbon transistors
Joshua O. Island, Michele Buscema, Mariam Barawi +7
Here, we isolate thin TiS3 ribbons, a layered direct band gap semiconductor (1.1 eV, well suited for detection all across the visible spectrum), thus far almost unexplored. We fabr…
Fast and broadband photoresponse of few-layer black phosphorus field-effect transistors
Michele Buscema, Dirk J. Groenendijk, Sofya I. Blanter +3
Few-layer black phosphorus, a new elemental 2D material recently isolated by mechanical exfoliation, is a high-mobility layered semiconductor with a direct bandgap that is predicte…
Isolation and characterization of few-layer black phosphorus
Andres Castellanos-Gomez, Leonardo Vicarelli, Elsa Prada +10
Isolation and characterization of mechanically exfoliated black phosphorus flakes with a thickness down to two single-layers is presented. A modification of the mechanical exfoliat…
