Electrical detection of hyperbolic phonon-polaritons in heterostructures of graphene and boron nitride
Achim Woessner, Romain Parret, Diana Davydovskaya +11
Light properties in the mid-infrared can be controlled at a deep subwavelength scale using hyperbolic phonons-polaritons (HPPs) of hexagonal boron nitride (h-BN). While propagating…
Electrical 2π phase control of infrared light in a 350nm footprint using graphene plasmons
Achim Woessner, Yuanda Gao, Iacopo Torre +8
Modulating the amplitude and phase of light is at the heart of many applications such as wavefront shaping, transformation optics, phased arrays, modulators and sensors. Performing…
Tuning quantum non-local effects in graphene plasmonics
Mark Lundeberg, Yuanda Gao, Reza Asgari +11
The response of an electron system to electromagnetic fields with sharp spatial variations is strongly dependent on quantum electronic properties, even in ambient conditions, but d…
Out-of-plane heat transfer in van der Waals stacks: electron-hyperbolic phonon coupling
K. J. Tielrooij, N. C. H. Hesp, A. Principi +20
Van der Waals heterostructures have emerged as promising building blocks that offer access to new physics, novel device functionalities, and superior electrical and optoelectronic…
