← ScienceWhich outcome occurs while injecting dopants into silicon in semiconductor fabrication?
A)Lattice strain altering orbital overlap✓
B)Increased electron-phonon scattering rate
C)Formation of metallic silicide compounds
D)Vacancy cluster induced crystal twinning
💡 Explanation
When dopants are introduced into silicon, the dopant atoms distort the silicon crystal lattice, causing lattice strain due to the size difference, thus affecting the electron orbitals overlap because electrons are forced closer or further apart. Therefore, altered orbital overlap occurs, rather than other options such as phonon, metallic formation, or twinning without altering the base lattice structure.
