The Academic Centre for Materials and Nanotechnology invites you to another Krakow Condensed Matter Seminar and ACMiN Seminar event that will take place on March 29, 2023 at 9:00 in hybrid form.

The lecture titled Metal iodates under high-pressure will be delivered by Professor Daniel Errandonea (Departamento de Física Aplicada─ICMUV, MALTA Consolider Team, Universitat de Valencia, Spain).

Participation

  • On-site: ACMiN (30 Kawiory Street, D-16 building, second floor, auditorium room 1.02A)
  • Online: MS Teams platform (link)

Abstract

The goal of this talk is to report a systematic and balanced review of the progress made in recent years on the high-pressure behavior of iodates, a group of materials with multiple technological applications and peculiar behaviors under external compression. This talk will include results obtained from multiple characterization techniques which include X-ray diffraction, Raman and infrared spectroscopy, optical-absorption and resistivity. The discussion of the results from experiments will be combined with density-functional theory calculations which have been shown to be a very useful tool for the interpretation of experimental data. Throughout the presentation many of the phenomena observed will be connected to the presence of a lone electron pairs of the iodine atoms in the studied iodates. The presence of the lone electron pairs plays a crucial role in the high-pressure behavior of iodates and it is associated with many of the phenomena to be discussed, in particular with the pressure-induced changes in the character of iodine-oxygen bonds, which causes many physical properties to behave nonlinearly.
