  • Optoelectronic and photonic devices require materials with multiple, often conflicting functionalities, leading to integration challenges. Here, the authors demonstrate that layered PdSe2 is suitable for infrared photodetection, light guiding and photothermal applications due to its peculiar semimetallic band structure.

  • The authors combine films of two-dimensional semiconductors, which exhibit excitonic spectral features, with SiO2/Si Fabry-Perot resonators in order to realize topological phase singularities in reflection. Around these singularities, the reflection spectra demonstrate rapid phase changes while the structure behaves as a perfect absorber.
