They noted that the ratio of the D peak intensity to that of the G peak varied inversely with La: I (D)/I (G)= C(¦Ë)/La where C (488 nm) ¡« 4.4 nm from Refs. [26,91,92,44]. There are few experimental verifications of TK where La is known independently by X-ray diffraction (XRD) [26,93¨C97], and the minimum La for which TK has been directly verified is ¡«2 nm. |
