Which outcome occurs as lattice spacing uniformly decreases in a Silicon nanowire?

A)Band gap energy increases overall✓

B)Electron mobility increases rapidly

C)Wire becomes mechanically more brittle

D)Thermal conductivity decreases directly

💡 Explanation

Band gap increases because decreased lattice spacing enhances quantum confinement, modifying the electronic band structure. Consequently, the energy difference for electron excitation increases therefore the band gap widens, rather than alternative outcomes from changed electron mobilities or thermal conduction.
