← ScienceWhich risk increases when gallium arsenide transistor size decreases?
A)Increased electron quantum tunneling impacts✓
B)Elevated lattice vibrational scattering magnitude
C)Greater electron effective mass alteration
D)Enhanced piezoelectric polarization fluctuation
💡 Explanation
Decreasing transistor size increases the probability of electron quantum tunneling because the width that electrons must traverse decreases; therefore, quantum tunneling becomes a significant factor, rather than being negligible under normal operating conditions.
