In this work, we investigate the field emission characteristics of carbon nanotube forest on three types substrate: (1) mirror polished, (2) chemically etched (large pattern) and (3) chemically etched (small pattern) Si substrate. The surface morphology of CNTs forest was characterized by scanning electron microscopy (SEM), surface chemical state and electronic structure phase analyzed by X-ray photoelectron...
In this study, carbon nanotubes (CNTs) were synthesized on a catalyst of zinc oxide (ZnO) nanorods prepared with a hydrothermal process. The surface morphology of the CNTs was studied with scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and the structural properties and chemical compositions of the CNTs were studied with Raman spectroscopy and energy dispersive spectrometer...
One promising application of CNTs in microelectronics is to use vertically aligned CNT (VACNT) arrays as novel thermal interface materials (TIMs). No doubt that the vertical alignment makes the best of the extremely high longitudinal thermal conductivity of individual CNTs; however, it is the CNT/substrate interface that exerts the main restriction on phonon transport through a TIM layer. There are...
