New advancesin engineering nanostructures open up a unique path to discovery and innovation as well as commercialization. This is because (a)asnanostructures become smaller than a fundamental physical length scale, conventional theory may no longer apply, leading to new phenomena, new knowledge, and revolutionary products in a broad range of disciplines; and (b)new high-throughput and low-cost nanomanufacturing methods will not only accelerate R&D, but also are essential to turninventions in laboratories intocommercial products.
The presentation will give some examples of the author’s 30 years research in nanostructures engineering, particularly, the pioneer researches in ultra-transistors (world smallest transistors, transistor scaling, velocity overshoot, quantum devices, and single electron memories), and the inventions of new magnetic data storage paradigm (bit-patterned media) and path-changing high-throughputmanufacturing methods (nanoimprint and self-perfection by liquefaction (SPEL)).
