High quality (hetero-) epitaxy usually needs mono-crystalline substrates. The typical substrates, often from binary materials like GaAs, InP, InAs, GaSb or even Ge, cause severe constraints due to the limited choice of lattice constants, thermal misfit or simply because of cost. In this session, solutions to overcome these limitations by either engineered substrates or lattice mismatched (metamorphic) epitaxy shall be discussed. Ideally the epitaxy layer or device quality for growth on such engineered substrates or metamorphic buffers is presented.

The energy cost of storing and moving data is enormous, and is growing at such a rapid pace that within a few years the power demand may overwhelm some developed nations. Non-volatile memory (NVM) and neuromorphic computing are enabling critical advances in this area, but there are many scientific and technological challenges. This conference will cover the materials challenges of different memory technologies, from the fundamental processes and mechanisms, to industry perspectives on materials specifications and manufacturing.

Materials Challenges for Memory

poster

The recent years have seen a revolution in the science and practice of crystal growth. Novel mechanisms of nucleation and growth have decoded mysteries that have puzzled the community for ages. Elaborate processes and advanced techniques have birthed materials with unprecedented properties and exciting applications. Rationales developed within the crystal growth realm have illuminated longstanding conundrums in geology, biology, and medicine. 

These jointly-held conferences are the premier forums to discuss the huge modern advances in all aspects of crystal growth, both in the bulk and as epitaxial films. We will continue the tradition of numerous ACCGE and OMVPE meetings and bring together the topmost experts in the field from industry, academia, and government laboratories. Joining the two conferences affords an exceptional opportunity to present and discuss original results and provides a venue for newcomers to embrace the hot, new advances in science and technology. Our format is designed to maximize interaction among leading specialists and the wider crystal growth community, with oral and poster sessions as well as plenary and invited speakers to provide a broad picture of the up-to-date developments in the field.

III-V Wide Bandgap Nitride Semiconductors and Devices II : III-Nitride Properties and Characterization

This last decade, microfluidics technology has proved its efficiency to study crystallization fundamentals in chemistry and biology. This symposium will give an opportunity to the crystal growth community to present and discuss about the latest advances in this field of research. Presentations and discussions will focus on experimental and theoretical aspect of phase separation and crystal growth studies.

Research on the synthesis and the applications of various low-dimensional materials (0D, 1D, and layered 2D materials) are the themes of this symposium. These materials' unique properties, differing or exceeding those of their bulk crystal counterparts, are of potential scientific and technological importance. Materials of central importance to this symposium include 2D layered materials such as graphene, boron nitride, transition metal dichalcogenides and oxides, topological insulators superconductors, Xenes, etc., as well as their 0D and 1D counterparts and various heterostructural combinations. Due to widespread interest, a Special Topic Session on 2D magnetism is organized. Magnetism plays pivotal roles for a wide range of significant technologies such as data storage and biomedical imaging and continues to exhibit new phenomena in emerging materials at reduced dimensions. Magnetic 2D layered materials, experimentally discovered in 2017, are ideal platforms where both crystalline structural order and long-range magnetic order coexist in the atomic-thin region. The integration of 2D magnets with disparate electronic and photonic 2D materials opens up remarkable opportunities for designer quantum heterostructures with previously inaccessible magnetoelectric and magneto-optical properties. This Special Topic Session will collect abstracts on 2D magnet physics and modeling, various synthesis and characterization of 2D magnets and related heterostructures, and quantum transport and tunneling properties of 2D materials-based spintronic devices. This symposium aims to explore, through the contributions of leading researchers, new methodologies and breakthroughs in low-dimensional materials and identify constraining issues to future development.
