Which 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.
