Comparison between methods to measureintensity modulator Vpi
Gilles Feugnet, Salma Essawab, Jimmy Pennanech +6
We describe and compare in this paper two common methods to measure the half-wave voltage (Vpi) of an electro-optical modulator versus RF frequency of the driving electronic signal…
Free-electron laser-based extended wide-field mid-infrared photothermal imaging for biomedical and microplastic analysis
Anooj Thayyil Raveendran, Subham Adak, Artem Shydliukh +8
Wide-field mid-infrared photothermal (MIP) imaging offers rapid labelfree chemical contrast for biomedical and polymer analysis. However, its field of view (FOV) is limited by the…
Temperature-dependent refractive index of AlGaAs for quantum-photonic devices near the bandgap
Moritz Langer, Sai Abhishikth Dhurjati, Martin Bauer +6
We present an experimental method to determine the refractive index of (x = 0.0 - 0.5) from 300 K to 4 K across the 500 - 1100 nm wavelength range. The values ar…
Fermi surface evolution in Weyl semimetal t-PtBi probed by transverse transport properties
F. Caglieris, M. Ceccardi, D. Efremov +8
The combination of non-trivial topology and superconductivity opens to novel quantum devices. The discovery of intrinsic materials where such properties appear together represents…
The phase diagram of CeRhAs for out-of-plane magnetic field
P. Khanenko, J. F. Landaeta, S. Ruet +10
The heavy-fermion superconductor CeRhAs () shows two superconducting (SC) phases, SC1 and SC2, when a magnetic field is applied para…
X-ray photoemission spectrum, electronic structure, and magnetism of UCuSi
J. A. Morkowski, G. CheÅkowska, M. WerwiÅski +3
The room temperature X-ray photoemission spectrum of the ferromagnetic compound UCuSi (T = 100 K) was measured using an Al K source. Related theoretical spectra we…
