Outline of Final Research Achievements

We investigated the deposition characteristics of some polymer materials, low-molecular materials and MgZnO inorganic semiconductor thin-films by three-electrode electrospray deposition, called nano mist deposition (NMD) that improves the controllability of deposition. The surface morphology of the layers were relatively smooth and the device characteristics of the MoO3/F8BT/ZnO inorganic-organic hybrid LED fabricated using NMD were comparable to those using spin-coating. We also demonstrated an Alq3/NPB layer stack without interface erosion and developed multi-mode NMD which applicable for smooth layer deposition of low-molecular thin-film with low-affinity of substrate. We also demonstrated a possibility of disposable optical functional sheet by fabricating OLEDs on coated paper and PET sheet.
