| Summary: | 碩士 === 國立臺灣大學 === 應用物理所 === 101 === We combine organic molecules of 3,4,9,10-perylenetetracarboxylic(PTCDA) with iron atoms on an Au (111) substrate in ultra-high vacuum conditions, we can measuring Fe-PTCDA ladder ,chain, and network by scanning tunneling microscopy(STM). By scanning tunneling spectroscopy (STS), Fe-PTCDA network and pure PTCDA on Au (111) have peak shift compare with pure PTCDA on Au (111).
In order to understand this we compare the STS curves of PTCDA molecule connect with different number of adjacent molecules and discover this will influence the
charge transfer.
