英文摘要	Tunable biaxial stresses, both tensile and compressive, are applied to a single layer graphene by utilizing piezoelectric actuators. the gruneisen parameters for the phonons responsible for the d, g, 2d and 2d' peaks are studied. the results show that the d peak is composed of two peaks, unambiguously revealing that the 2d peak frequency (omega(2d)) is not exactly twice that of the d peak (omega(d)). this finding is confirmed by varying the biaxial strain of the graphene, from which we observe that the shift of omega(2d)/2 and omega(d) are different. the employed technique allows a detailed study of the interplay between the graphene geometrical structures and its electronic properties.
