What else can I help you with?
What are the various equation methods of enriching uranium 235 from its natural form?
- centrifuging - gaseous diffusion - thermal diffusion - electromagnetic separation - expansion from nozzles - laser enrichment - ion exchangers - distillation
How do you construct an n type semiconductor?
An n-type semiconductor is formed by doping a pure semiconductor (silicon or germanium, for example) with atoms of a Group V element, typically phosphorus or arsenic. The dopant may be introduced when the crystal is formed or later, by diffusion or ion implantation.
What is annealing in IC fabrication?
Annealing is the heat treatment given to a semiconductor material. Annealing is the process by which the lattice damages are repaired. The damages are generally done by ion implantation on semiconductor material.
What is the difference between electric charge and ion?
An electric current goes through an electric circuit, if it is closed.
What is mineral ion?
ions that plants need for supprt and growth
What is the difference between diffusion and ion implantation?
Diffusion is the mixing of two materials by the natural movement of the particles.Implantation is a forced action for the introduction of an item (or partcle) in other object (material).
Advantages of ion implantation over diffusion?
Ion implantation allows for precise control of dopant concentration and depth, resulting in more uniform doping profiles compared to diffusion processes. It also enables the doping of materials that are difficult to dope by diffusion. Additionally, ion implantation can be performed at lower temperatures, reducing the likelihood of damaging the material being processed.
What is the difference between diffusion potential and nernst potential?
Diffusion potential arises due to concentration differences of ions across a membrane without considering membrane permeability. Nernst potential, on the other hand, takes into account both concentration differences and membrane permeability for a specific ion to calculate the equilibrium potential at which the net flow of that ion is zero.
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
What is the difference between an Ion and an Molecule?
Ions are charged.
What is the difference between pyrophosphate and bisphosphate?
The ion biphosphate is (HPO4)2-.The ion pyrophosphate is (P2O7)4-.
Can allow diffusion of gases?
gas ion transfer or diffusion through cells.
How is facilitated diffusion similar to diffusion ion channels?
Facilitated diffusion and diffusion ion channels both involve the movement of substances down a concentration gradient without requiring energy input. However, facilitated diffusion involves the assistance of carrier proteins to transport specific molecules, while diffusion ion channels are specialized proteins that form pores in cell membranes for specific ions to pass through.
Why sodium ion diffuse slowly than a chlorine ion?
Sodium ions are larger and more hydrated than chloride ions, which slows down their diffusion rate through a medium. The presence of hydration shells around sodium ions leads to more friction and obstacles during diffusion, compared to the smaller and less hydrated chloride ions.
What is a dimer in ion implantation?
In ion implantation, a dimer refers to two atoms that are implanted simultaneously into a target material. This can be beneficial for certain applications where the presence of two atoms together can create specific interactions or properties in the material. Dimer implantation can be used to tailor the material's properties by controlling the concentration and distribution of the two types of atoms.
What is the difference between the formation of a positive ion and a negative ion?
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
What is the difference between Chloride and callcium?
Chloride is an ion of chlorine plus one electron. In solution, calcium is an ion missing two electrons.
