Which phenomenon prevents complete reaction of reactants in scanning tunneling microscope induced oxidation of surface dangling bond orbitals:?

A)Quantum mechanical phase interference
B)Self-limiting negative feedback loop
C)Tip-induced band gap renormalization
D)Electrostatic charge repulsion effects

💡 Explanation

When oxidation starts via STM, a self-limiting negative feedback loop inhibits completion because increased oxide thickness reduces tunneling current to the dangling bond, slowing the reaction rate as surface charge accumulates inhibiting oxidation further. Therefore slow reaction results, rather than alternative quantum, electronic effects.
