Electroluminescence and Energy Transfer Mediated by Hyperbolic Polaritons
L. Abou-Hamdan, A. Schmitt, R. Bretel +26
Under high electrical current, some materials can emit electromagnetic radiation beyond incandescence. This phenomenon, referred to as electroluminescence, leads to the efficient e…
Diamond quantum magnetometer with dc sensitivity of < 10 pT Hz toward measurement of biomagnetic field
N. Sekiguchi, M. Fushimi, A. Yoshimura +10
We present a sensitive diamond quantum sensor with a magnetic field sensitivity of in a near-dc frequency range of 5 to 100~Hz. This sensor is b…
Giant ultra-broadband photoconductivity in twisted graphene heterostructures
Hitesh Agarwal, Krystian Nowakowski, Andres Forrer +12
The requirements for broadband photodetection are becoming exceedingly demanding in hyperspectral imaging. Whilst intrinsic photoconductor arrays based on mercury cadmium telluride…
Monolayer WS electro- and photo-luminescence enhancement by TFSI treatment
A. R. Cadore, B. L. T. Rosa, I. Paradisanos +14
Layered material heterostructures (LMHs) can be used to fabricate electroluminescent devices operating in the visible spectral region. A major advantage of LMH-light emitting diode…
Strong Inter-valley Electron-Phonon Coupling in Magic-Angle Twisted Bilayer Graphene
Cheng Chen, Kevin P. Nuckolls, Shuhan Ding +31
The unusual properties of superconductivity in magic-angle twisted bilayer graphene (MATBG) have sparked enormous research interest. However, despite the dedication of intensive ex…
Dilemma in All-optical Characterization of Single-layer NiI2 Multiferroics
Yucheng Jiang, Yangliu Wu, Jinlei Zhang +3
Matters Arising in Nature on "Evidence for a single layer van der Waals multiferroic". The search for two dimensional multiferroic materials is an exciting yet challenging endeavor…
