1. Low-concentration detection of CO2 using suspended silicon waveguides in the mid-IR

Author

Lin, Pen-Sheng, Quellmalz, Arne, Huang, Po-Han, Parhizkar, S., Negm, N., Suckow, S., Ottonello-Briano, F., Lemme, M. C., Niklaus, Frank, Gylfason, Kristinn, Lin, Pen-Sheng, Quellmalz, Arne, Huang, Po-Han, Parhizkar, S., Negm, N., Suckow, S., Ottonello-Briano, F., Lemme, M. C., Niklaus, Frank, and Gylfason, Kristinn

Abstract

We show detection of CO2 concentrations as low as 500 ppm using a suspended silicon photonic mid-IR waveguide. The performance is enabled by the low propagation loss (2.35 ±0.25) dB/cm permitting sensing with waveguides up to 7 cm in length., QC 20230607

2. Enhancing closures in scala 3 with spores3

Author

Haller, Philipp and Haller, Philipp

Abstract

The use of closures, a core language feature of functional programming languages, has become popular in the context of concurrent and distributed programming. Using closures in a concurrent or distributed setting increases safety hazards, however, due to captured variables. Previous work proposed spores, enhanced closures that increase safety by constraining their environment using types. This paper presents Spores3, a completely new library-based implementation of spores for Scala 3. It is shown how the new design is enabled by a unique combination of several new features in Scala 3. Moreover, Spores3 contributes a new, portable approach to serializing closures based on type classes. Its implementation supports the same serialization approach on both the JVM and the JavaScript backends of Scala., QC 20230613

Abstract

We study electron correlation driven superconductivity on a decorated honeycomb lattice (DHL), which has a low-energy flat band. On doping, we find singlet superconductivity with extended-s, extended-d and f-wave symmetry mediated by magnetic exchange. f-wave singlet pairing is enabled by the lattice decoration. The critical temperature is predicted to be significantly higher than on similar lattices lacking flat bands. We discuss how high-temperature superconductivity could be realized in the DHL materials such as Rb3TT. 2 H2O and Mo3S7(dmit)3., 4 pages, 4 figures + Supplemental material

Abstract

The control on the charge transport properties of ternary organic photovoltaic P3HT:PCBM:QBT devices is enabled by modulating the distribution of P3HT polymorphs in the device photoactive layers. Negligible amounts of QBT induce striking modifications in the P3HT lamellar stacking direction, forming both densely packed and non-densely packed P3HT chains. The former reduce the charge carrier recombination rate, enabling an increased fill factor and short-circuit device photocurrent.
