Ⅳ. Results of Planning Research
(1) Completion of source patent pending about display core-materials and synthesis technology based on laser.
∙ 8 core patent applications on core-materials for display and synthesis technology based on laser-material interactions (one in international patent, seven in domestic patents) are pending by project research step.
∙ Patent 1 : Patent application on the block-copolymer aligned conjugated quantum dot. (US-62/246,219)
∙ Patent 2 : Patent application on the quantum dot nanostructure manufacturing method via laser-induced annealing and quantum dot pattern manufacturing method. (KR-10-2015-0143605)
∙ Patent 3 : Patent application on the block copolymer conjugated quantum dot precursor materials. (KR-10-2015-0143604)
∙ Patent 4 : Patent application on the high mobility organic semiconductor materials and electron transfer layers manufactured via laser-induced molecular orientation. (KR-10-2015-0143606)
∙ Patent 5 : Patent application on the fabrication of nano-pattern by laser-induced self-assembly of block copolymer on light absorption layer. (KR-10-2015-0115131)

(2) Laser material interaction evaluation research based on multiscale simulation.
∙ Molecular kinetics is performed for the proof of molecule alignment in direction of electric field through heating and slow cooling of polymer substrate when DC electric field is applied. Solid phase pyrimidine becomes liquid phase with mobility, freedom and alignment in the direction of electric field after applying electric field and heating. This result suggests that the experiment of molecule alignment in specific direction only scanned area by laser be possible if the external electric field applied and melt it by laser locally.
∙ The research of free energy estimation of liquid and solid phase binary system about various temperature and composition and calculation of binary phase diagram are an essential part to investigate the phase change possibility via the binary phase diagram calculation of binary system which 2 elements are combined. In this research, gold-silicon binary force field model and application technologies have been developed and binary phase diagram calculation method involved with nanoscale effects is being developed to investigate the phase separation possibility of laser-absorbed few nanometer depth.
∙ A basic model is developed to estimate the various patterns theoretically for the block copolymer conjugated quantum dot patterning which is necessary to develop the light emitting materials.
∙ For the sintering via laser and the development of electrode, preliminary modeling about the laser absorbance of the various material structure and the estimation of the light intensity of the various space are performed. This modeling can be applied to the investigation of the optimized laser injection conditions later on.

(3) Discovery of phase separation of binary compounds by laser
∙ Separation phenomenon of solid phase crystal binary compounds into a single element in vertical direction by laser is discovered. Phase separation phenomena of polymer or metal alloy are random direction separation with several hundred nanometer or micro scale. Our research group discovered the phase separation phenomenon of homogeneous atomic scale thickness (~2nm) and conducts researches about new channel material synthesis to surpass the existing material properties via this new synthesis method.
