Unreconstruct

It is interesting that in cases where the surface does not have the geometry and periodicity of the bulk-terminated plane, the interaction of hydrogen with surface atoms is strong enough to unreconstruct the complicated reconstruction patterns.

The argument for describing these surfaces as bulk terminated, as chlorine adsorption is known to unreconstruct silicon surfaces, was presented in chapter 1.

Hydrogen adsorption can unreconstruct surfaces and passivate surface dangling bonds, and thus can change the surface properties dramatically.
