Raman spectroscopy for characterization of Fe/Al2O3 nanostructures

In this work, Raman spectroscope is used to characterize the Fe/Al2O3 catalysts to find the structure differences between different thicknesses of catalysts. These catalysts are used for carbon nanotube (CNT) growth in thermal chemical vapor deposition (CVD) method. In the previous CNT growth experi...
