Electronic Structure of InAs and InSb Surfaces: Density Functional Theory and Angle-Resolved Photoemission Spectroscopy

The electronic structure of surfaces plays a key role in the properties of quantum devices. However, surfaces are also the most challenging to simulate and engineer. Here, the electronic structure of InAs(001), InAs(111), and InSb(110) surfaces is studied ...

Spectrally Selective Mid-Wave Infrared Detection Using Fabry-Perot Cavity Enhanced Black Phosphorus 2D Photodiodes

Christophe Ballif, Quentin Thomas Jeangros, Wei Yan

Thin two-dimensional (2D) material absorbers have the potential to reduce volume-dependent thermal noise in infrared detectors. However, any reduction in noise must be balanced against lower absorption from the thin layer, which necessitates advanced optic ...

Active Near-Infrared Imaging for Spatio-Temporal Monitoring of a Solid Oxide Cell in Operation

Jan Van Herle, Stefan Diethelm, Guillaume Jeanmonod

The characterization of solid oxide cells (SOCs) relies mainly on direct-current (DC) and alternating-current (AC) methods that provide only average surface electro-chemical responses. As such, the spatial distribution is not well captured and the complexi ...

Bloch Surface Waves Using Graphene Layers: An Approach toward In-Plane Photodetectors

Hans Peter Herzig, Myun Sik Kim, Richa Dubey, Babak Vosoughi Lahijani

A dielectric multilayer platform was investigated as a foundation for two-dimensional optics. In this paper, we present, to the best of our knowledge, the first experimental demonstration of absorption of Bloch surface waves in the presence of graphene lay ...

High-Contrast Infrared Absorption Spectroscopy via Mass-Produced Coaxial Zero-Mode Resonators with Sub-10 nm Gaps

Hatice Altug, Aurélian Michel John-Herpin, Sunghwan Kim

We present a wafer-scale array of resonant coaxial nanoapertures as a practical platform for surface-enhanced infrared absorption spectroscopy (SEIRA). Coaxial nanoapertures with sub-10 nm gaps are fabricated via photolithography, atomic layer deposition o ...

Field-induced charge separation dynamics in monolayer MoS2

Andras Kis, Dumitru Dumcenco, Yen-Cheng Kung, Dmitry Ovchinnikov, Daniele Vella, Dragan Mihailovic

The absorption spectra of 2D semiconductors are dominated by excitons with binding energy of several hundreds of meV. Nevertheless, even single layers show an appreciable photovoltaic effect and work as the active material in high sensitivity photodetector ...

Comparison of Thermal Detector Arrays for Off-Axis THz Holography and Real-Time THz Imaging

Christoph Peter Hauri, Mostafa Shalaby

In terahertz (THz) materials science, imaging by scanning prevails when low power THz sources are used. However, the application of array detectors operating with high power THz sources is increasingly reported. We compare the imaging properties of four di ...

Time-sliced perturbation theory for large scale structure I: general formalism

Sergey Sibiryakov, Diego Blas Temino, Mikhail Ivanov

We present a new analytic approach to describe large scale structure formation in the mildly non-linear regime. The central object of the method is the time-dependent probability distribution function generating correlators of the cosmological observables ...
