报告简介：

Atomic-layer-by-layer molecular beam epitaxy (ALL-MBE) （原子层精度分子束外延技术） is a new technique developed in the last few decades to synthesize functional quantum materials, including high-temperature superconductors (HTS), other complex oxides, and two-dimensional materials such as graphene and borophene. It also enables one to synthesize novel metastable materials that cannot be synthesized by standard methods. Several examples will be presented of ALL-MBE alchemy - the creation of artificial materials with novel and unique electronic properties. The ability to engineer the materials at a single-atomic monolayer level has also enabled important discoveries of novel physical phenomena and effects in HTS cuprates and beyond [1].

This talk is aimed at a broad audience, so the emphasis will be on painting the big picture and pointing at the goals we hope to reach eventually. One of these is to discover a new material that superconducts at room temperature and ambient pressure（室温常压超导）. Another is to build an HTS-based, desktopsize neuromorphic computer, approaching the human brain's neuron count (10-100 B) and power consumption (10 W), as the ultimate platform for Artificial Intelligence of the future（人工智能计算机）.
