Methodology
  • This repository includes raw data from the following measurements: spectroscopic ellipsometry, Fourier transform infrared spectroscopy, and energy dispersive spectroscopy. Detailed methods regarding measurement collection are found in the accompanying citation, and below.

  • Spectroscopic Ellipsometry: Ellipsometry measurements on MgO and BZHO thin films were taken with Woollam M-2000 ellipsometer. This experimental technique is used to capture the optical properties from room temperature up to 1100 °C. Using the Woollam analysis software, CompleteEase, we fit raw ellipsometry measurements to extract the refractive index. The refractive index is described with a simple polynomial. In this database, we keep the coefficients of this polynomial (at each temperature) stored in text files, which are accessed with analysis file 3.

  • Energy Dispersive Spectroscopy (EDS): EDS was used to spatially map the concentration of ionic cations in our MgO/BZHO superlattice structure. This was used to demonstrate negligible cation diffusion in our superlattice structure before and after annealing at 1100 °C in dry air. In this database, we store linescans of cation profiles across the superlattice structure.

  • Fourier Transform Infrared Spectroscopy (FTIR): Fourier transform was utilized in two ways for this paper. First, we use conventional benchtop FTIR to analyze the spectral transmission of BZHO/MgO photonic crystals before and after annealing at 1100 °C in dry air. Also, we utilized FTIR to capture the thermal emission of NiO:MgO with and without at MgO/BZHO photonic crystal. Here, we upload the emissivity of this structure and calculate a hypothetical TPV efficiency based on an empirical model.
Description
  • This repository includes the analysis code and raw data for a paper titled "Nanophotonic control of thermal emission under extreme temperatures in air, " in Nature Nanotechnology (see citation). In our work, well defined structure-color effects guided the design of a nanostructure containing stratified layers of two oxides, magnesium oxide (MgO) and barium zirco-hafnate (BaZr0.5Hf0.5O3 or BZHO). The repeating layers were tuned in such a way to manipulate incident infrared wavelengths. The infrared is the spectral range in which heat (in the form of electromagnetic radiation) is emitted from objects. Therefore, the nanostructure serves as a way to alter the thermal emission spectrum of hot objects, controlling how much heat can flow. This can have significant impacts on a range of technologies, such as thermal photovoltaics (TPVs), which generate electricity from the infrared light emission of hot objects (compared to visible light emission from the sun in solar photovoltaics). We envision that our MgO/BZHO nanostructure can be paired with a thermal emitter in TPV systems to beneficially manipulate the flow of infrared light, leading to more efficient electricity production. To characterize the thermal stability of this structure, we had to characterize the thermal stability and optical performance at room temperature and at 1100 °C. This lead us to conduct several experiments using ellipsometry, TEM, EDS, and FTIR.
