Which risk increases when designing molecular electronic components at very small scales?

💡 Explanation

Increased electron tunneling becomes significant as component size decreases because electron's wave function penetrates insulating barriers due to quantum tunneling, rather than electrons flowing using band transport. Therefore, signal integrity degrades; rather than improved quantum effects.
