Abstract The electronic and optical properties of single-layer (SL) tungsten disulfide (WS $$_2$$ 2 ) in the presence of substitutional Holmium impurities (Ho $$_{\text{W}}$$ W ) are studied. Although Ho is much larger than W, density functional theo

Designing electronically asymmetric environment across monolayer graphene enhances the photo-thermoelectric effect and enables efficient infrared photodetection. Here, the authors report a photodetector based on CVD grown nano-patterned graphene with

We showed in past work that nanopatterned monolayer graphene (NPG) enables spectrally selective thermal emission in the mid-infrared (mid-IR) from 3 to 12 $\mu$m. In that case the spectral selection is realized by means of the localized surface plasm

We showed in past work that nanopatterned monolayer graphene (NPG) can be used for realizing an ultrafast (∼100 ns) and spectrally selective mid-infrared (mid-IR) photodetector based on the photothermoelectric effect and working in the 8-12 μm reg

Due to the low photon energy, detection of infrared photons is challenging at room temperature. Thermoelectric effect offers an alternative mechanism bypassing material bandgap restriction. In this article, we demonstrate an asymmetric plasmon-induce

We present a proof of concept for a spectrally selective thermal mid-IR source based on nanopatterned graphene (NPG) with a typical mobility of CVD-grown graphene (up to $3000$ cm$^2$V$^{-1}$s$^{-1}$), ensuring scalability to large areas. For that, w

Enhancing light-matter interaction by exciting Dirac plasmons on nanopatterned monolayer graphene is an efficient route to achieve high infrared absorption. Here, we designed and fabricated hexagonal planar arrays of nanoholes and nanodisks with and
