Energetics of molecular assemblies and realistic scanning tunneling spectroscopic (STS) simulation of two-dimensional materials
Changwon Park
Center for Nanophase Materials Science, Oak Ridge National Laboratory
Uniform and defect-free molecular film is highly desirable in the application of organic electronics. During the molecular deposition on substrates, a subtle balance between various interactions determines the assembling patterns. Two interesting examples (Metal Phthalocyanines and Tetracyanoquinodimethane) showing the drastic effect of molecule-substrate interaction will be presented with first-principles total energy analysis.
I will also show nonintuitive scanning tunneling spectroscopies (STS) of two-dimensional materials and molecules and suggest a few ideas on realistic STS simulations.
