These measurements describe a material's dynamic response to a small applied electric field. In contrast, nonlinear dielectric materials are widely used for their responses to large applied fields, including switching in ferroelectric materials, and field-tuning of the permittivity in paraelectric materials. These behaviors are described by nonlinear permittivity. Nonlinear permittivity measurements are fraught with technical challenges because of the complex electrical coupling between a sample and its environment. Here, we describe a technique for measuring the complex nonlinear permittivity that circumvents many of the difficulties associated with other approaches. We validate this technique by measuring a the nonlinear permittivity of a tunable Ba0.5Sr0.5TiO thin film up to 40 GHz and comparing our results with a phenomenological model. These measurements provide insight into the dynamics of nonlinear dielectric materials down to picosecond timescales.", "distribution": [{"description": "Data shown in Figure 6 of the paper \"Measurements of nonlinear polarization dynamics in the tens of GHz\"", "downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig6_Y2_midas.csv", "format": "column data, comma-delimited.", "mediaType": "text/csv", "title": "Data for Figure 6"}, {"description": "Data shown in Figure 6 of the paper \"Measurements of nonlinear polarization dynamics in the tens of GHz\"", "downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig7_eps_midas.csv", "format": "Column data, comma delimited", "mediaType": "text/csv", "title": "Data for Figure 7"}, {"description": "Frequency-dependent data shown in Figure 8 of the paper \"Measurements of nonlinear polarization dynamics in the tens of GHz\"", "downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig8_eps2_freq_dep_midas.csv", "format": "Column data, comma delimited", "mediaType": "text/csv", "title": "Frequency-dependent data for Figure 8"}, {"description": "Python script to generate plots in Figure 2.", "downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig2_calculation_midas.py", "format": "text file containing python script", "mediaType": "text/plain", "title": "Script to generate plots in Figure 2"}, {"description": "Readme file describing data.", "downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/readme.txt", "mediaType": "text/plain", "title": "readme"}, {"description": "Voltage-dependent data shown in Figure 8 of \"Measurements of nonlinear polarization dynamics in the tens of GHz\"", "downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig8_eps2_V_dep_midas.csv", "format": "Column data, comma delimited", "mediaType": "text/csv", "title": "Voltage-dependent data for Figure 8"}, {"downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig2_calculation_midas.py.sha256", "mediaType": "text/plain", "title": "SHA256 File for Script to generate plots in Figure 2"}, {"downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig6_Y2_midas.csv.sha256", "mediaType": "text/plain", "title": "SHA256 File for Data for figure 6"}, {"downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig7_eps_midas.csv.sha256", "mediaType": "text/plain", "title": "SHA256 File for Data for figure 7"}, {"downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig8_eps2_V_dep_midas.csv.sha256", "mediaType": "text/plain", "title": "SHA256 File for Voltage-dependent data for Figure 8"}, {"downloadURL": "https://data.nist.gov/od/ds/7589389138C4687EE0532457068193C91963/fig8_eps2_freq_dep_midas.csv.sha256", "mediaType": "text/plain", "title": "SHA256 File for Frequency-dependent data for Figure 8"}], "identifier": "7589389138C4687EE0532457068193C91963", "issued": "2024-07-19", "keyword": ["Microwave Materials", "loss", "nonlinear measurements", "permittivity", "tunability"], "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2019-02-22 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "references": ["https://dx.doi.org/10.1103/PhysRevApplied.13.044026"], "theme": ["Materials:Materials characterization", "Metrology:Electrical/electromagnetic metrology"], "title": "Data for: ?Measurements of nonlinear polarization dynamicsin the tens of gigahertz?"}
