Laboratory of Materials Morphology and Structure Investigations (MMoSt Lab) has been established at the Institute of Solid State Physics, University of Latvia in 2017 and focuses on the study of materials structure, morphology and composition using modern experimental and theoretical methods, employing also high performance cluster computing.

Our experimental possibilities include but are not limited to several techniques such as scanning and transmission electron microscopies, scanning probe microscopies and confocal microscopy, X-ray diffraction and synchrotron-radiation X-ray absorption spectroscopy.

We use advanced theoretical calculations and simulations of experimental data to gain insight on the structure-property relationships in materials.

Our laboratory is also involved in the teaching process at the University of Latvia and provides students with opportunities to participate in research activities during Bachelor, Master and Doctoral level programs.

Molecular dynamics and reverse Monte Carlo simulations of X-ray absorption spectra (EXAFS/XANES).

We develop advanced data analysis methods for extracting structural information from X-ray absorption spectra. 

Investigation of structure-property relationships of advanced functional materials.

We conduct systematic studies based on modern experimental and theoretical methods to better understand and optimize the functional properties of various oxide materials.

Local structure relaxation in nanomaterials.

We study the effect of crystallite size reduction on the local atomic and electronic structure in nanomaterials using modern experimental techniques and theoretical simulations.

Radiation damage in materials.

We study the formation of nano-defects and the modification of related properties in LiF single-crystals by irradiating them with energetic (MeV-GeV) ions.
