How do bonds break?

The underlying question that motivates my current work is,

What are the forces on atoms and ions associated with surfaces that result in these particles leaving or reattaching to the surface when stimulated with an outside agent?

These surfaces may be surrounded by very high vacuum or by an aqueous solution. The stimulation that assists the motion of the atoms or ions may be a laser or electron beam, or it might be a very sharp, hard tip pushing on the surface. In all cases, the rate of particle removal or attachment, the speeds or energies of the particles involved, and even the direction they … » More …
