Scholarship Hanchen Huang has conducted research in a range of disciplines – including theoretical nanorods synthesis and nuclear physics; experimental nanorods synthesis and nuclear physics; and atomistic simulations of nanorods synthesis, solid mechanics, and radiation damage. His most notable contribution is in the area of science and technology of metallic nanorods synthesis. A.1 Science and Technology of Metallic Nanorods In this area, Hanchen Huang’s contributions span the entire spectrum of concept discovery, formulation of analytical theories based on the new concept, experimental discovery of smallest and well-separated metallic nanorods under the guidance of the analytical theories, invention of metallic glue technology based on the experimental discovery, and commercialization of the technology through a startup company MesoGlue Inc. The following provides the definition of scientific challenge, and description of each contribution across the entire spectrum. • Definition of Scientific Challenge: Around the turn of 20th and 21st centuries, “nano” had become fashionable. Many nanostructures were synthesized, without full understanding of what made these nanostructures nanoscale in dimension. For clean scientific understanding with minimum ambiguity, Hanchen Huang chose to focus on the simplest materials system and cleanest process – metallic nanorods synthesis through physical vapor deposition (PVD) in vacuum. For such metallic nanorods, the kinetic factor that keeps the dimension of nanorods at the nanoscale in dimension is surface diffusion. For simple metals like Cu and Ag, the theoretical value of surface diffusion distance is on the order of 10-100 micro meters (micron), but the experimental value of nanorods diameter is on the order of 10-100 nano meters (nm). The three orders of magnitude discrepancy between theory and experiment cannot be explained by small inaccuracy of the theory. Then, what is the origin of this discrepancy? • Concept Discovery: In 2002, Hanchen Huang and his group have proposed a new concept of diffusion of surface adatoms over multiple-layer steps and named it three-dimensional Ehrlich-Schwoebel (3D ES) barrier, in reference to the classical (independent) contributions of Ehrlich’s group and Schwoebel’s in 1960s in discovering the extra diffusion barrier over monolayer surface steps. Through atomistic calculations, Hanchen and his group have demonstrated that the 3D ES barrier will slow down surface diffusion by about 1,000,000 times at typical processing temperatures. Consequently, the diffusion distance is reduced by 1,000, so the new theoretical value of diffusion distance becomes 10-100 nm in agreement with the experimental value of nanorods diameter. This new concept of 3D ES barrier has been referred to as “…the final piece in our understanding of the rules that govern how atoms move from one layer to another as films or crystals grow” in a subsequent Nature highlight in 2002. • Analytical Theories: Based on the new concept of 3D ES barrier, Hanchen Huang and his group have formulated an analytical theory of nanorod diameter. Two characteristics of this theory are that: (1) it is based on the new concept of 3D ES barrier, and (2) it is analytical – that is, it expresses nanorod diameter as an analytical function of deposition parameters. Further, they have developed an analytical theory of nanorods separation. The second theory is not conceptually new, but its analytical form had never been available before (only numerical solutions were available). The combination of these two theories reveals an interesting critical length scale, below which the separation is smaller than the diameter so nanorods would be replaced by thin 2 film. One year before these two theories were developed, Hanchen Huang and his students – like many other
