The main difference is atoms that which are channelled through the diffusing process where the atoms stick to the molecular structure of a material this only happens in interstitial diffusion where in vacancy diffusion the atoms reppelled away hence the word vacancy.

Interstitial diffusion occurs when atoms or molecules move through the spaces between existing atoms in a crystal lattice, while vacancy diffusion occurs when atoms or molecules move via empty spaces (vacancies) within the lattice. In interstitial diffusion, the diffusing species occupies lattice sites temporarily, whereas in vacancy diffusion, atoms move by hopping from one vacancy site to another.

Compare Interstitial and Vacancy Atomic mechanism for Diffusion?

In interstitial diffusion, atoms move through the interstitial sites between existing atoms, which requires less energy for movement. In vacancy diffusion, atoms move by hopping into neighboring vacancies, which requires more energy as it involves breaking and reforming bonds. Interstitial diffusion is typically faster than vacancy diffusion due to lower energy requirements.


What is the difference between vacancy and self interstitial crystalline defects?

Vacancy defects are missing atoms within a crystal lattice, while self-interstitial defects are extra atoms that occupy interstitial spaces within the lattice. Vacancies result in a decrease in density, while self-interstitials increase density. Both types of defects can affect the material's mechanical and electrical properties.


What is singly ionized oxygen vacancy?

A singly ionized oxygen vacancy refers to a situation where one electron is missing from an oxygen ion in a crystal lattice, leading to a positive charge on the vacancy site. This can affect the material's properties by altering its electronic structure and impacting its conductivity or optical properties. In materials science, the presence of oxygen vacancies is often manipulated to engineer specific functionalities in materials.


Name the type of point defect that occurs in a crystal of zinc sulphide?

A common type of point defect that occurs in a crystal of zinc sulphide is a vacancy defect. In this defect, an atom is missing from its lattice position, creating a gap or a vacancy in the crystal structure.


What is oxygen relation energy in emc anictain formula?

Oxygen relation energy, as part of EMC Anatase, denotes the formation energy of an oxygen vacancy in a material. It quantifies the energy required to create an oxygen vacancy in the crystal lattice and is an important parameter for understanding the material's properties, such as conductivity or catalytic activity.
