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…
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…
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…
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…
