Non-contact nanothermometry based on X-ray absorption spectra
Bezkontakta nanotermometrija, izmantojot rentgenabsorbcijas spektrus

Project coordinator: Dr.phys. A.Kalinko
Total cost: 300 000 EUR
Duration (years): 2023-2025
Funding institution: Latvian Council of Science
Funding number: lzp-2022/1-0608

Today's technological demands in areas such as microelectronics, micro-optics, photonics and nanomedicine have reached a point where the use of traditional thermometry is becoming a limiting factor, if not an obstacle to accurate temperature measurements. In this fundamental project, we propose to develop a new methodology based on the use of X-ray absorption spectroscopy to measure the temperature of a material by analysing the fine-structure amplitude of the X-ray absorption spectrum. The proposed method for temperature measurements is focused on, but not limited to, temperature mapping in multilayer chips and plasmonic nanoparticles. The project is compliant with the Research and Innovation Strategies for Smart Specialisation (RIS3) of Latvia in the area of "Smart materials, technologies and engineering systems".
