Metadata describing the data used in the research publication 'Silicon photonic crystal thermal emitter at near infrared wavelengths'.

Metadata describing the data used in the research publication ‘Silicon photonic crystal thermal emitter at near infrared wavelengths’, in the journal Scientific Reports. The data presented in the publication can be broken up into four sections according to the figures the data is presented in. First, is the data presented in Fig. 3(a-c) all of this data is generated using 3D simulation software. Second, is the data plotted in Fig. 5, this data is experimentally measured data. Third, is the data plotted in Fig 6(a), which is more simulation results. And finally, fourth, is the data plotted in Fig. 7(a), which again, is experimentally measured.

All the data is in the file format '.csv'.

Total list of files:
1) Figure3a_ReflectionSpectrum_Undoped.csv
2) Figure3b_ReflectionSpectrum_Doped.csv
3) Figure3b_AbsorptionSpectrum_Doped.csv
4) BandDiagramDoped.csv
5) DataSet_Emission_RawData.csv
6) DataSet_Emission_SmoothCorrectedNormalisedData.csv
7) IR_Source_RawData.csv
8) IR_Source_SmoothCorrectedNorm.csv
9) BandDiagramEmission.csv

Section 1. Figure 3 (a) - (c):
The data files relevant for this section are:
1) Figure3a_ReflectionSpectrum_Undoped.csv
2) Figure3b_ReflectionSpectrum_Doped.csv
3) Figure3b_AbsorptionSpectrum_Doped.csv
4) BandDiagramDoped.csv

The data plotted in Fig. 3(a,b) was generated using the 3D FEM simulation software COMSOL while the data plotted in Fig. 3(c) was produced using the FDTD software know as MEEP. Details about the computational domain and structural parameters for both simulations can be found in the manuscript itself.

The data plotted in Fig. 3(a) is ‘Figure3a_ReflectionSpectrum_Undoped.csv’. For Fig. 3(b) the red curve is ‘Figure3b_ReflectionSpectrum_Doped.csv’ and the blue plot is ‘Figure3b_AbsorptionSpectrum_Doped.csv’. For each of the three csv data files the x-axis data (wavelength) is the first column of the matrix and the second column is the y-axis data either reflection or absorption.

The data points plotted in Fig. 3(c) are ‘BandDiagramDoped.csv’. Here the first column corresponds to the x-axis wavenumber with the remaining columns the y-axis data.

Section 2. Figure 5:
The data files relevant for this section are:
1) DataSet_Emission_RawData.csv
2) DataSet_Emission_SmoothCorrectedNormalisedData.csv
3) IR_Source_RawData.csv
4) IR_Source_SmoothCorrectedNorm.csv

‘DataSet_Emission_RawData.csv’ contains the raw data measured directly from the optical spectrum analyser (OSA). ‘DataSet_Emission_SmoothCorrectedNormalisedData.csv’ contains the data plotted in Fig. 5, i.e. the four thermal emission spectra. In both of these files the x-axis data (wavelength) is the first column. The next four columns are the emission y-axis values for 1046 K, 1093 K, 1106 K and 1117 K respectively.

The same applies to the infra-red thermal source data plotted in Fig. 5. ‘IR_Source_RawData.csv’ contains the raw data measured directly with the OSA. ‘IR_Source_SmoothCorrectedNorm.csv’ contains the data plotted in Fig. 5. Again, the first column is the x-axis data (wavelength) and the 2nd column is the y-axis emission data.

All of the experimentally measured raw data was first smoothed and then normalised before plotted in Fig. 5.

Section 3. Figure 6:
The data files relevant for this section are:
1) BandDiagramEmission.csv

‘BandDiagramEmission.csv’ is the band diagram data plotted in Fig. 6. As in Fig. 3(c), the first column corresponds to the x-axis wavenumber value with the remaining columns the y-axis data.

Section 4:
The data files relevant for this section are:
1) ReflectionWhileHeating_RawData.csv
2) ReflectionWhileHeating_SmoothNorm.csv

As in section 2, ‘ReflectionWhileHeating_RawData.csv’ is the data measured directly by the OSA. And ‘ReflectionWhileHeating_SmoothNorm.csv’ is the data after smoothing and normalisation and is the data plotted in Fig. 7 of the paper. In both files the first column is the x-axis (wavelength) data. the next eight columns are the y-axis reflection data for 0 V, 30 V, 50 V, 56 V, 60 V, 66 V, 70 V and 76 V respectively.
