Title: Physical origin of electronic phase separation in manganites and device application
Abstract: For most of the strongly correlated systems, including colossal magnetoresistive manganites and high-Tc superconductors, the inhomogeneity of electronic phases are very general. Due to the strong coupling of spin, charge, orbital and lattice, the free energies of these electronic phases are quite close, resulting in a phenomenon named electronic phase separation (EPS). In the case of manganites, the ferromagnetic metallic phase and antiferromagnetic insulating phase coexist, and the characteristic length scale of EPS ranges from nanometer (such as La1-xCaxMnO3) to micrometer (such as (La1-yPry)1-xCaxMnO3). The micrometer length scale is much larger than those of structural defects or nonuniform distribution of chemical dopants. It remains controversial whether phase separation requires quenched disorder for its realization. Using a layer-by-layer superlattice growth technique, we fabricate a fully chemically ordered “tricolor” manganite superlattice [(LaMnO3)1/(CaMnO3)1/(PrMnO3)1]n. Remarkably, the fully ordered manganite has an antiferromagnetic insulating ground state, and does not exhibit phase separation, while its presence is pronounced in isovalent alloyed La1/3Pr1/3Ca1/3MnO3 manganite films [1]. In addition, the partially chemically ordered “bicolor” superlattice [(La5/8Ca3/8MnO3)2/(Pr5/8Ca3/8MnO3)1]n reduces the length scale of EPS domains by a factor of 10 compared to the alloy [2, 3]. Our study provides direct evidence that the disorder induced by isovalent chemical doping plays the decisive role in stabilizing EPS in the manganite system. Based on the understanding of the physical origin of the complex magnetic domains in oxides, we have developed various methods to control the domain patterns in oxides and fabricated multi-bit memory device that can also carry out logic operations [4].
Experience: Lifeng Yin is professor and deputy dean of department of physics, Fudan University. He received his B.S. and Ph.D. degree from Fudan university at 2001 and 2007 respectively.

His main research interest lies in condensed matter and materials physics, as well as the applications of materials and devices, especially focuses on the surface and interface of complex oxides and their emergent phenomena under spatial confinement. He has revealed that the physical origin of electronic phase separation in manganites is related with chemical ordering using a layer-by-layer superlattice growth technique. He develops advanced instruments, such as cryogen free spin polarized scanning tunneling microscopy and magnetic exchange force microscopy, industrially-scaled large size pulsed laser deposition system and so on.

Title: III-nitride Optoelectronic Devices for 6G
Abstract: In recent years, high-speed optical wireless communications (OWC) have been identified as an essential part of communication technologies for next generation 6G wireless network owing to the increasing demand for faster data transmission speeds. As one of the fast-growing techniques in OWC, visible light communication (VLC) offers the unique advantages of ultra-high data rate, unregulated and secure channels, free of EM interference. Besides the potential for achieving high data rate free-space communication links, i.e., the Li-Fi network, laser-based VLC, or visible laser light communication (VLLC) technology can also enable underwater wireless optical communications (UWOC) for many important applications. The presentation focuses on the development of III-nitride devices and related physical layer techniques for VLC. The talk will feature the development of novel transmitters, including the superluminescent diodes (SLDs), laser diodes, VCSELs, and receiving technologies, such as optical antenna and PD array. The outlook of future trends will also be discussed in this talk.

Title: Exciton phase transition in 2D semiconductors
Abstract: The strong excitonic effect in Two-dimensional (2D) semiconductors creates many interesting light-matter interaction phenomena. Different exciton densities result in different interactions among excitons that can drastically change the light-matter interactions in the 2D semiconductors. Similar to atoms or molecules, excitons with different densities and interactions can experience phase transitions. In this talk, I will systematically discuss how the optical properties such as emission and exciton transport in 2D semiconductors change from exciton gas phase to ionized electron-hole plasma (EHP) and finally condense to the exotic electron-hole liquid (EHL) phase. Especially, the unique large exciton binding energy in monolayer MoS2 enable us to realize room-temperature EHL and the critical temperature can reach up to 700K. I will also discuss the exciton phase diagram of monolayer MoS2 that differs from conventional bulk semiconductors and quantum wells. The phase diagram reveals the pathway and driving force of exciton phase transition in monolayer MoS2: from exciton gas to exciton Mott transition due to screening effect, and then dense EHP condense into EHL due to thermodynamics of the nonequilibrium photocarriers. The room temperature exciton phase transitions in monolayer MoS2 lead to drastically different emission and exciton transport properties, allowing novel optoelectronic and quantum devices to be developed.
Experience: Yiling Yu is interested in understanding the fundamentals of strong exciton related many-body effects in low dimensional semiconductors, and explore the related exotic optical and quantum phenomena in low dimensional materials and their heterostructures. Based on the understandings, we use light, strain, and devices fabrication to further tuning the optical and quantum properties of the material for achieving novel two dimensional photonic and optoelectronic devices.

Title: Titanium Dioxide Nanomaterials for advanced environmental applications
Abstract: Titanium dioxide (TiO2) is one of the most attractive transition-metal oxides because of its superior physical and chemical properties, which has been widely applied in environmental clean-up (photocatalytic pollution removal) as well as antibacterial/antiviral coating applications. The performance of TiO2 in these applications highly depends on its structural, electronic, optical, and morphological as well as the surface properties (exposed facets). Great effort has been devoted to adjust these properties and apparent progress has been made on the synthesis of the 0-, 1-, 2-, and 3-dimensional nanostructured TiO2 materials. Today, the presentation will cover the synthesis of TiO2-based nanomaterials and their environmental related applications.
