Abstract
Langmuir-Blodgett films of standard amphiphilic molecules like cadmium arachidate (CdA) and nickel arachidate (NiA) are deposited on differently passivated (OH-, H- and Br-passivated) Si(001) surfaces and molecular packing information from the top layer of all the films are obtained using atomic force microscopy (AFM). Molecular-resolution images, containing the information of molecular packing, are clearly obtained from the CdA films as the top surfaces are atomically flat, however, for the NiA films the information of the surface modulations are actually obtained due to the lack of top surface flatness. Triclinic packing of CdA molecules are obtained from the OH- and Br-terminated Si (OH-Si and Br-Si respectively), whereas herringbone packing are obtained from the H-terminated Si (H-Si). However, relatively loosely packing of NiA molecules causes molecular tilting which creates surface modulations and depending upon the substrate type the modulation covers nearly four (H-Si), six (Br-Si) and twelve (OH-Si) molecular area.
