Tunable graphene phononic crystal
Jan N. Kirchhof, Kristina Weinel, Sebastian Heeg +4
In the field of phononics, periodic patterning controls vibrations and thereby the flow of heat and sound in matter. Bandgaps arising in such phononic crystals realize low-dissipat…
In situ functionalization of graphene
Kyrylo Greben, Sviatoslav Kovalchuk, Ana M. Valencia +7
While the basal plane of graphene is inert, defects in it are centers of chemical activity. An attractive application of such defects is towards controlled functionalization of gra…
Neutral and charged excitons interplay in non-uniformly strain-engineered WS
Sviatoslav Kovalchuk, Moshe G. Harats, Guillermo López-Polín +3
We investigate the response of excitons in two-dimensional semiconductors subjected to controlled non-uniform strain fields. In our approach to non-uniform strain-engineering, a WS…
