Notes Expression for hole concentration in valence band The hole concentration in the valence band is a measure of the number of empty states, or holes, that are available for electrons to occupy in the valence band of ...
Notes Fermi Level of carrier concentration The carrier concentration refers to the number of electrons or holes (i.e., positively charged vacancies in the valence band) in a material. In a doped semiconductor, the carrier concentration is ...
Notes Double well levels For the double well potential, the WKB approximation can be applied separately in each well and in the barrier region between the wells. The resulting energy levels depend on the ...
Notes WKB approximation for Barrier Tunneling The WKB approximation, short for Wentzel–Kramers–Brillouin approximation, is a powerful method in quantum mechanics for approximating the solutions to the Schrödinger equation. The WKB approximation …
Notes Relativistic Lagrangian for a charged particle in electromagnetic field. The Lagrangian describes the dynamics of the system and is used in the Lagrangian formulation of classical mechanics to derive the equations of motion of the particle. The principle of ...
Notes Effective mass of an electron in solids In solid-state physics, the concept of effective mass is used to describe the behavior of electrons in a crystal lattice. The effective mass of an electron in a solid is ...
Notes Interpretation of mass neutron with fermi theory of beta decay In 1934, fermi made a successful theory of β decay based on Pauli's neutrino hypothesis. Fermi suggested that- The neutrino's rest mass affects how the spectrum is shaped. The ...
Notes Briet Wigner Resonance formula The Breit-Wigner formula, also known as the Breit-Wigner resonance formula, is a mathematical expression used to describe the probability of a resonance occurring in a particle physics experiment. It …
