Current thermal interface materials including solders, greases, and phase change materials do not have the mechanical compliance required to fill cavities, and thermal conductance necessary to dissipate heat generated in modern microelectronic devices.The inability to dissipate heat properly from the microprocessor device creates a thermal bottleneck which limits device efficiency and leads to early life degradation. Individual The most widely available and cost effective means of producing carbon nanotubes arrays is by chemical vapor deposition (CVD). This experimental study varied the ferrocene catalyst sublimation temperature over a range of 100ºC -180ºC, in CVD growth, to determine the impact on structural formation of vertically aligned carbon nanotube arrays. The diameter distribution, areal density, array height, and CNT density are calculated using measurements from scanning electron microscope and transmission electron microscope images to assess array quality. Raman spectroscopy was used as a tool to quantify the amount of disordered carbon within the array. It is found that decreasing the sublimation temperature improved the carbon nanotube arrays for thermal interface material applications using the current growth procedure.
