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.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-09-20t08:15:24z no. of bitstreams: 1 stretchable graphene.pdf: 2215834 bytes, checksum: aa2442b1126fe1f9dd8f610c64a6b6cf (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-09-20t08:28:16z (gmt) no. of bitstreams: 1 stretchable graphene.pdf: 2215834 bytes, checksum: aa2442b1126fe1f9dd8f610c64a6b6cf (md5); made available in dspace on 2010-09-20t08:28:16z (gmt). no. of bitstreams: 1 stretchable graphene.pdf: 2215834 bytes, checksum: aa2442b1126fe1f9dd8f610c64a6b6cf (md5) previous issue date: 2010; 国际
