According to the Stanford University thesis of Bradford Pate looking at diamond cleaved under ultrahigh vacuum with Low Energy Electron Diffraction, stable diamond surface terminates in C-H. Silicon does the same thing in hydrofluoric acid bath, Si-H rather than Si-F expected on purely bond strength arguments.
