← ScienceWhich risk increases when silicon crystals contain dislocations?
A)Lowered electron mobility occurs✓
B)Increased Hall effect magnitude
C)Enhanced piezoelectric response shown
D)Elevated thermal conductivity observed
💡 Explanation
Dislocations scatter electrons, therefore the electron mobility decreases because electrons collide more frequently with lattice imperfections, rather than contribute to directed current flow; altered Hall or thermal responses are secondary effects.
