Condensed matter

The development of the process for making semiconductors and metal structures at nanoscale extended the field of condensed matter from bulk matter down to nanoscale. Much effort of the theoretical reserchers working in material structure, composing the Sampa Group and the Nanomol Group , is made in this direction. They aim to understand the basic principles underlying the structural, electronic, optical, magnetic, and transport properties of a variety of materials ranging from semiconductors, metals, and oxides, to the nanostructured materials such as nanowires, nanotubes, and nanoribbons. Starting from quantum mechanics, they use analytical methods and computer simulation approaches to calculate the desired properties. Geologically relevant materials at the nanometer scale are also studied. Experimental work in nanostructures is attained in several laboratories. In the Semicondutor New Materials Laboratory, the reserchers carry out the growth and characterization of semiconductor in the form of heterostructures, nanocrystals, quantum dots, and quantum rings. The main research of the Thin Films Laboratory is the study of micro and nanostructures in thin films. The study of magnetic properties of thin films and microscopic magnetic particles is one of the purposes of the Magnetic Materials Laboratory. Studies of new materials at very low temperatures under high magnetic fields are made possible in the Low Temperature and Solid State Laboratory. In this laboratory, the Group of Low Temperatures and the Group of Phase Transitions and Supercondutivity carry out their experimental work in spintronics, nanostructures, Bose-Einstein condensation, and strongly correlated electron systems. Crystalline solids, simple liquids, and gases are the states of condensed matter with the simplest structures. Other systems, such as amorphous solids, liquid crystals, polymers, and gels, have a much more complex structure. The Crystallography Laboratory aims to study the structure of these systems by X-ray diffraction and small angle scattering.
