Carbon Nanotubes has superior properties in reinforce piezoelectric effects to increase mechanical strength at the layer interfaces. The author has proposed the relation between the refractive index of carbon nanotube and piezoelectric lattice vibration coefficient on dispersion relation. We have studied the ionic polarization of carbon materials at optical frequencies which are associated with nano piezo electronics lattice vibration. Recent studies of one of the allotropes of carbon i.e., Graphene have shown the piezoelectric properties. This relation is applied to the study of piezoelectric lattice vibration in carbon nanotubes. This paper presents the Piezoelectric effects on carbon nanomaterial. Using Atomic Force Microscopy, we demonstrated the piezoelectric effect of multi-walled carbon nanomaterial under the compression method. This effect is caused by the incident of light on the surface of materials which leads to coherent acoustic Phonons induced diffraction. This way we evaluate the piezoelectric coefficient in the infrared region on single and multilayer of carbon nanomaterials. This theoretical study offers various fundamental research on advancements in carbon-based nanomaterials piezotronics devices.
