Osaka time: 16:00-18:00
Groningen time: 9:00-11:00
Chair: Prof. Tadashi ItohProf. Akira Harada, Graduate School of Science (16:00-16:55 (O) / 9:00-9:55(G))(Field: macromolecules, self-assembly, self-healing)
Title: Supramolecular materials
Abstract: Macromolecular recognition is classified as main-chain recognition and side chain
recognition. Main-chain recognition is involved in the formation of polyrotaxanes in which somecyclic molecules are threaded onto a polymer chain. We have studied on the relative movement ofcyclic parts and a linear chain. We can control the rates and the direction of the cyclic parts on apolymer chain. In addition, we have achieved macroscopic self-assembly and self-healing systems
through side-chain recognition.

Friday, 29 Oct. 2021
Osaka time: 16:00-18:00
Groningen time: 9:00-11:00
Chair: Prof. Tadashi ItohProf.Yasufumi Fujiwara, Graduate School of Engineering (16:00-16:55 (O)/ 9:00-9:55 (G))(Field: rare-earth-doped semiconductors, OMVPE growth, LED, luminescence, energy transfer)
Title: Fundamentals of light-emitting diode with rare-earth-doped semiconductors
Abstract: After the groundbreaking invention of blue and green light-emitting diodes (LEDs)
employing nitride semiconductors (InxGa1-xN/GaN), there has been a strong demand to develop
red LEDs using nitride semiconductors. We have focused on europium (Eu) ions that have been
widely used as an activator for red phosphor, and have succeeded in growing Eu-doped GaN(GaN:Eu) layers with high crystalline quality by atomically-controlled organometallic vapor phase
epitaxy (OMVPE), as well as developing the world’s first red LED that operates at room
temperature using GaN:Eu as the active layer. This lecture will cover current status ofconventional GaN-based LEDs and the GaN:Eu red LED, present understanding of Eu
luminescent sites formed in GaN and future strategies for the improved light output of the LEDs.

Title: Functional inorganic nanomaterials
Abstract: As a special class of materials, inorganic nanomaterials consist of particles of metals,metal oxides, metal chalcogenides (metal sulfides, selenides, or tellurides) or halide perovskites
with at least one dimension in the 1- to 100-nanometer (10−9 m) range. These nanomaterials arehighly interesting because they exhibit properties that bridge the gap between bulk and molecular
structures. Unlike their bulk counterparts, nanomaterials exhibit tunable size- and shape-dependent
optical, electronic, and magnetic properties. Because of these unique properties, nanomaterials arebeing explored to address key global challenges in areas such as energy conversion, catalysis,
medicine, sensing, and environmental remediation.

Title: Basics and applications of electronic phase change oxides
Abstract: Phase change materials enable rapid switching between different structural phases,
resulting electric properties switching. Some classes of materials are interesting on switching
between different electronic/spin phases itself, such as Mott insulator- metal transition, and theirelectronic phase change would produce new classes of devices. This part of the lecture will focus
on electronic phase change phenomena on transition metal oxides.
Topics will be included, ・Physics and material science on structural and metal/insulator transitionof VO2 as a prototype material, ・Brief review of phase change phenomena on transition metaloxides (vanadate, manganite, nickelate, ferrite, ruthenate, etc.), ・External field induced electronic
phase change phenomena, ・Switching/Memristive /Biology-inspired /Photonic devices based onelectronic phase change materials.

Title: Quantum design of nanomaterials.
Abstract: Quantum mechanics is determining the properties of materials on the atomic scale.
Macroscopic systems on the other hand can be described well with classical dynamics. In this talkquantum mechanical effects on the nanometer length scale will be discussed. First, thedelocalization of electronic wave functions over nanoscale super molecular structures will bediscussed. Secondly, the effect of quantum interference between such wave functions will bediscussed and how this phenomenon can be used to design materials with desirable properties andsuppressed (or enhanced) charge recombination in heterojunction materials and exciton-excitonannihilation in light-harvesting systems.
