Why, when Silicon changes to Porous silicon, does the energy gap change to direct? Why is the energy gap in porous silicon increased?

Its clear that the surface of porous increased and energy gap depends on type of porous Silicon (Nonporous, Mesoporous and Macroporous) I think, this increase in energy gap comes from SiO2 bond...
