Basis
Crystal basis: The structure of the crystal is determined by: 1. Crystal Basis (Point group) 2. Lattice Geometry (Translational symmetry) Together, the point group symmetry combined with the translational symmetry…
Lattice Planes and Miller Indices
What is a Lattice Plane? In crystallography, a lattice plane of a given Bravais lattice is a plane (or family of parallel planes) whose intersections with the lattice (or any…
Dielectric constant of dielectric materials
What is Dielectric? A dielectric is a material which has poor electrical conductivity but inherits an ability to store an electrical charge(due to Dielectric polarization). Thus exhibiting only displacement current making it…
Reciprocal Lattice
Reciprocal Lattice The reciprocal lattice represents the Fourier transform of another lattice (usually a Bravais lattice). In normal usage, the initial lattice (whose transform is represented by the reciprocal lattice)…
Applications of nanotechnology
Applications of nanotechnology Nanotechnology is being used in developing countries to help treat disease and prevent health issues. The umbrella term for this kind of nanotechnology is Nano-medicine. Nanotechnology is…
Temperature dependence of critical field
Temperature dependence of critical field The superconducting state cannot exist in the presence of a magnetic field greater than a critical value, even at absolute zero. This critical magnetic field is strongly correlated…
Temperature dependence of resistivity in superconducting materials
Resistivity Resistivity is known as specific electrical resistance or volume resistivity. It can be defined as the intrinsic property of a given material that shows how it opposes the flow of…
Conductivity of Semiconductors
Conductivity of Semiconductors Every atom has an outer band of electrons, known as the valence band. In metals, the electrons from this valence band are not confined to the atom…
