Which risk increases significantly when graphene sheets debond?

A)Increased thermal boundary resistance
B)Enhanced electrical conductivity laterally
C)Improved mechanical tensile strength
D)Higher resonant frequency oscillations

💡 Explanation

Debonding increases thermal resistance because phonon transport weakens across the interfaces, therefore heat dissipation becomes less efficient, rather than the electrical conductivity improving or structural integrity being enhanced due to weakened Van der Waals forces.
