Application of Solid-State Physics The most important among them are: Electronic devices such as mobiles and computers. Optical devices such as lasers and fibre optics. Magnet based devices such as Magnetic Resonance Imaging (MRI) and vibrating devices..
What is symmetry in solids applied physics?
Symmetry and Symmetry Operations Crystal symmetry describes the similarity in the lattice points and environment throughout the Crystal • symmetry operation is that which transform the Crystal to itself. The symmetry operations are translation, rotation, reflection and inversion..
What is the introduction to solid state physics and its applications?
Introduction. The branch of physics that deals with the study of rigid solid matter are called Solid state physics. It is done through a variety of methods including quantum mechanics, electromagnetism, metallurgy and crystallography and forms the theoretical foundation of materials science as a whole..
A crystal has an inversion symmetry if for every lattice point at r we have corresponding lattice points at (-r). The inversion centre is denoted by “l”.
History. A separate field going by the name of physics emerged in 1940, with the establishment of the Division of Solid State Physics (DSSP) within the American Physical Society. Soon after war II, large communities of solid-state physicists emerged in Europe, especially in England, Germany, and also the Soviet Union.
This structure can be investigated using a range of crystallographic techniques, including X-ray crystallography, neutron diffraction and electron diffraction.
How are crystalline solids held together?
The crystalline solids are held together by various types of bonds depending upon the size and electronegativity of the constituent elements
Among the bonds, there exist four types
These bonds occur in solids made up of atoms differing by a large amount in terms of electronegativity
How is crystallography used in Materials Science?
Crystallography is used by materials scientists to characterize different materials
In single crystals, the effects of the crystalline arrangement of atoms is often easy to see macroscopically, because the natural shapes of crystals reflect the atomic structure
In addition, physical properties are often controlled by crystalline defects
What is solid-state physics?
Solid-state physics is the study of rigid matter, or solids, through methods such as quantum mechanics, crystallography, electromagnetism, and metallurgy
It is the largest branch of condensed matter physics
Solid-state physics studies how the large-scale properties of solid materials result from their atomic-scale properties

Crystallography applied to solid state physics
Solid consisting of discrete molecules
A molecular solid is a solid consisting of discrete molecules. The cohesive forces that bind the molecules together are van der Waals forces, dipole-dipole interactions, quadrupole interactions, π-π interactions, hydrogen bonding, halogen bonding, London dispersion forces, and in some molecular solids, coulombic interactions. Van der Waals, dipole interactions, quadrupole interactions, π-π interactions, hydrogen bonding, and halogen bonding are typically much weaker than the forces holding together other solids: metallic, ionic, and network solids. Intermolecular interactions, typically do not involve delocalized electrons, unlike metallic and certain covalent bonds. Exceptions are charge-transfer complexes such as the tetrathiafulvane-tetracyanoquinodimethane (TTF-TCNQ), a radical ion salt. These differences in the strength of force and electronic characteristics from other types of solids give rise to the unique mechanical, electronic, and thermal properties of molecular solids.
Nuclear magnetic resonance crystallography is a method which utilizes primarily NMR spectroscopy to determine the structure of solid materials on the atomic scale. Thus, solid-state NMR spectroscopy would be used primarily, possibly supplemented by quantum chemistry calculations, powder diffraction etc. If suitable crystals can be grown, any crystallographic method would generally be preferred to determine the crystal structure comprising in case of organic compounds the molecular structures and molecular packing. The main interest in NMR crystallography is in microcrystalline materials which are amenable to this method but not to X-ray, neutron and electron diffraction. This is largely because interactions of comparably short range are measured in NMR crystallography.
Voronezh State University is one of the main universities in Central Russia
Building
Voronezh State University is one of the main universities in Central Russia, located in the city of Voronezh. The university was established in 1918 by professors evacuated from the University of Tartu in Estonia. The university has 18 faculties and an enrollment of 22,000 students from Russia, Europe, Africa, the Americas and Asia. Besides, the university has 6 research institutes and 16 research laboratories administered by the Russian Academy of Science. The university is composed of 10 buildings and 7 resident halls situated throughout the city. For over 90 years the University has trained more than 100,000 professionals.
