diffusion is high temperature process while ion implantation is low temperature process
Ion implantation can be the effect of ion irradiation.
- centrifuging - gaseous diffusion - thermal diffusion - electromagnetic separation - expansion from nozzles - laser enrichment - ion exchangers - distillation
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.
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.
An electric current goes through an electric circuit, if it is closed.

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).
Doping levels can be precisely controlled since the incident ion beam can be accurately measured as an electric current.
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
What is the difference between ammonia gas and an ammonium ion?

Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
I actually don't think it does. Diffusion is normally controlled by mass, and sodium atoms being less massive than chlorine atoms should diffuse more rapidly (the difference in mass between the neutral atom and the ion isn't enough to matter).

Ions are charged.

Nitrate ion is NO3-1 while Nitride is N-3.
Chlorite is ClO2- ion whereas chloride is Cl- ion
