https://lnkd.in/daaVVQVp Transition-metal dichalcogenides have drawn attention as possible frameworks for a wide range of applications. Recently, the introduction and rise to prominence of Janus monolayers and vertical heterostructures have allowed further tuning of the properties of these systems. To comprehensively explore these aspects, including excitonic and optoelectronic characterization, we present a theoretical study of the MX2/MX2, MXY/MX2, MX2 /MXY and MXY/MXY bilayer systems, where M = Mo, W; X = S, Se; Y = S, Se.

Did you know that our waveguide-integrated SNSPDs are available in two versions? To meet different needs, we have developed our Dena detector series, which can be used in a variety of applications. Our 19" rack-compatible detector system integrates a cryostat, vacuum system, compressor and electronics in a single package for a true all-in-one solution. For more sensitive environments, our compact tabletop version features a separate helium compressor to reduce heat, noise and vibration that can interfere with photon detection. Want to learn more?

The journal paper, “Empirical Characterization and Modeling of the Propagation Channel Inside the VIRC”, by Zaher MAHFOUZ, Robert Vogt, André B. J. Kokkeler, and Andrés Alayón Glazunov got published in IEEE Access journal. https://lnkd.in/eMQPaJxc The paper thoroughly investigates the radio propagation channel inside the VIRC for narrowband SISO systems operating in the range 670–2740 MHz, as in LPWANs. The investigation focuses on the 1st- and 2nd-order temporal and spectral channel characteristics: coherence time, Doppler spectrum, Doppler spread, frequency autocovariance function, coherence bandwidth, rejection rate of chi-squared goodness-of-fit test for Rician distribution, Rician K-factor, and channel gain. Besides the impact of the frequency of operation, the investigation considers the effect of the rotational speed of the VIRC motors and two loading conditions, on the channel characteristics. After of a full analysis of the measurement results, empirical models closely fitting the behavior of various investigated characteristics are proposed. For example, one of the developed models can be used in EMC characterization as a systematic method for evaluating the effectiveness of different VIRC stirring mechanisms. Moreover, several proposed models are essential for the next research step concerning the development of a VIRC-based cost-effective channel emulator for OTA-testing in LPWANs. #VIRC #OTA #EMC #LPWANs #Doppler #Rician

FEATURED PRODUCT: The Mid-IR Comb pushes precision metrology into the 3 – 14 μm spectral range, the so-called molecular fingerprint region. It enables high-sensitivity and high-accuracy measurements, such as mid-IR Fourier-transform spectroscopy (FTIR), nano-FTIR, mid-IR dual-comb spectroscopy, or frequency-locking of mid-IR quantum cascade lasers. The system provides up to 200 mW average optical power within a large spectral bandwidth of 50 to 300 cm−1. Menlo Systems #photonics

Fail! 2020, our first beamtime at the Swiss Light Source, granted for XLD measurements of the orbital polarization of SrVO3 films under opposite signs of strain. Despite the excitement, our expectations crashed onto the rocks of reality: we measured the same XLD signal for both compressive and tensile strain (spectra on the right, TEY. Expectation: mirror inversion). This led to an XPS surface study that we published a few years ago (referenced in the comments) that made us realize that the overoxidized near-surface region is much thicker (> 10 unit cells) than what we thought, and in fact our XLD results only probe this region (which has nothing to do with SrVO3). 2021, with this understanding, Cinthia Piamonteze (corresponding author) brilliantly suggested that we employ the less-common XEOL acquisition mode, which probes the entire thickness of the film. With this, we show for the first time the theoretically predicted mirror inversion, elucidating how strain can control which d orbitals the electrons prefer to occupy (spectra on the left). More importantly, our results illustrate how important it is to consider the near-surface region: it can skew the interpretation of various measurements (e.g. 'dimensional MIT' at low thickness), and derail implementation of correlated oxides in functional devices, most notably in field effect transistors. Now out in APL Materials (open access), with the full data sets available in the supplement https://lnkd.in/dQhMTY9f Congrats to lead author Lishai Neuman (Shoham), Maria Baskin, Yaron Kauffmann, Anna Zakharova, Teppei Yoshida, Shigeki Miyasaka and again, Cinthia Piamonteze whose genuine partnership has made this work possible.

New preprint out: This one took a long time & ended up being much longer than anticipated, but we are back to quantum effects & correlated two-electron systems (laser-induced inconsequential double ionization -- NSDI). Contains intra-channel interference conditions in NSDI that can be applied to arbitrary driving fields. https://lnkd.in/eqHWrY9J

While I'm not at IPAC24, the work that I did at CERN regarding the Beam Wire Scanners and a solution to them breaking due to beam induced heating is being presented by my colleagues Michela Neroni, Christine Vollinger, and Carlo Zannini. If you see them or the work I hope you support them and ask lots of interesting questions! 😊 Paper Titles: Mitigation of beam coupling impedance for the wire scanners in the CERN Super Proton Synchrotron - Christine Vollinger Impedance and thermal studies of the CERN SPS Wirescanners and mitigation of wire heating - Carlo Zannini #IPAC24
