Notes Expression for concentration of carrier in an intrinsic carrier in semi conductor. In an intrinsic semiconductor, the concentration of carriers (electrons and holes) is determined by the intrinsic carrier concentration, denoted as ni. The intrinsic carrier concentration is a …
Notes Deuteron problem The deuteron is also important for understanding the behaviour of nuclear forces, which are responsible for holding atomic nuclei together.The solution of the deuteron problem paved the way for ...
Notes Atomic scattering factor The atomic scattering factor depends on the electron density distribution of the atom, and describes how the incident radiation is scattered by the atom as a function of the angle ...
Notes The partial wave theory of low energy s wave n-p scattering The partial wave theory of low-energy s-wave neutron-proton (n-p) scattering is a theoretical framework used to describe the interactions between neutrons and protons when they are scattered at low …
Notes Spectrum of primary cosmic rays Primary cosmic rays are high-energy particles that originate from sources outside of our solar system and travel through space at close to the speed of light. These particles include protons, ...
Notes Relation between Nuclear potential and Range of nuclear force The nuclear potential is the potential energy associated with the nuclear force, which is the strong force that binds protons and neutrons together in the nucleus of an atom. The ...
Notes Ohm's law and electrical conductivity Let us consider an electron of mass m and charge '-e' characterized by wave vector k such that it is related with velocity v of electron by the relationmv ...
Notes Nearly free electron theory and origin of band gap The nearly free electron theory is a model that explains the behaviour of electrons in a crystal lattice. It assumes that the electrons in the crystal lattice are not tightly ...
