<b>Resumen de la charla:</b> In this seminar I will give a
tutorial on 2D semiconducting materials and I will motivate their
interest in optoelectronic and straintronic applications. The
first half of the talk will be devoted to provide a general
background about 2D materials: why to study them, how to fabricate
them, how to handle them, how to fabricate devices out of them,
etc. In the last part of the talk I will explain how 2D
semiconductors are very appealing because of their optoelectronic
properties and how the combination between these optoelectronic
properties and their unique mechanical properties makes them
extremely interesting for the emerging field of straintronics.
Strain engineering is an interesting strategy to tune a material’s
electronic properties by subjecting its lattice to a mechanical
deformation. Conventional straining approaches, used for 3D
materials are typically limited to strains lower than 2% in most
cases due to the low maximum strains sustained by brittle bulk
semiconducting materials. 2D materials can be literally stretched,
folded, bent or even pierced. This outstanding stretchability (and
the possibility of using dynamically varying strain) of 2D
materials promises to revolutionize the field of strain
engineering and could lead to "straintronic" devices – devices
with electronic and optical properties that are engineered through
the introduction of mechanical deformations. <br>

<p><b>Resumen CV: </b>Dr. Andres Castellanos-Gomez is a Tenured
Scientist in the Spanish National Research Council (CSIC). He
explores novel 2D materials and studies their mechanical,
electrical and optical properties with special interest on the
application of these materials in nanomechanical and
optoelectronic devices. He was awarded an ERC Starting Grant in
2017 and has been included in the Highly Cited Researchers 2018
list of Clarivate/WOS and selected as one of the Top Ten Spanish
Talents of 2017 by the MIT Technology Reviews. He has been also
recognized with the Young Researcher Award (experimental physics)
of the Royal Physical Society of Spain (2016).<b><br>
