| Research Abstract |
In a condition, nanocrystals coalesce with the concordance of crystal orientation. The clarification of this phenomenon which is called "Oriented attachment (OA) " would lead to the upgrading of thin film preparation using nanocrystals in wet process. We have investigated OA and obtained some results as follows. (1) As an evolution method for the surface structure of nanocrystals, we have applied a combination method with HR-TEM and electron tomography. We were able to obtain the structural change in a nanometer scale and demonstrate the effectiveness of this method. (2) Using an atomic resolution scanning transmission electron microscope, we were able to determine the nanocrystal polarity. The nanocrystal polarity has affected the growth. (3) As a result of investigating the control factor of OA, it was accelerated by additives besides the ligands.
