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…
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…
