Isolating hydrogen in hexagonal boron nitride bubbles by a plasma treatment
Li He, Huishan Wang, Lingxiu Chen +16
Atomically thin hexagonal boron nitride (h-BN) is often regarded as an elastic film that is impermeable to gases. The high stabilities in thermal and chemical properties allow h-BN…
Polariton Nanophotonics using Phase Change Materials
Kundan Chaudhary, Michele Tamagnone, Xinghui Yin +14
Polaritons formed by the coupling of light and material excitations such as plasmons, phonons, or excitons enable light-matter interactions at the nanoscale beyond what is currentl…
Pinpoint pick-up and bubble-free assembly of 2D materials using PDMS/PMMA polymers with lens shapes
Satoshi Toyoda, Teerayut Uwanno, Takashi Taniguchi +2
The key to achieving high-quality van der Waals heterostructure devices made by stacking two-dimensional (2D) layered materials lies in having a clean interface without interfacial…
Dry release transfer of graphene and few-layer h-BN by utilizing thermoplasticity of polypropylene carbonate for fabricating edge-contact-free van der Waals heterostructures
Kei Kinoshita, Rai Moriya, Momoko Onodera +5
The dry release transfer of two-dimensional (2D) materials such as graphene, h-BN, and TMDs is a versatile method for fabricating high-quality van der Waals heterostructures. Up un…
Graphene photodetector integrated on a photonic crystal defect waveguide
Simone Schuler, Daniel Schall, Daniel Neumaier +4
We present a graphene photodetector for telecom applications based on a silicon photonic crystal defect waveguide. The photonic structure is used to confine the propagating light i…
2D Semiconductor Nonlinear Plasmonic Modulators
Matthew Klein, Bekele H. Badada, Rolf Binder +8
A plasmonic modulator is a device that controls the amplitude or phase of propagating plasmons. In a pure plasmonic modulator, the presence or absence of a pump plasmonic wave cont…
