MULTI-PHYSICS ANALYSIS OF NANO-COMPONENTS BY FIRST-PRINCIPLE SIMULATION

摘要：

In recent years,materials in a nano-scale such as nano-films,nano-wires,and nano-dots have been manufactured not only by scientific interest but also by anticipation of future practical application.They possess different characteristic strength from their macro-scale counterparts (effect of extemai structure;shape).On the other hand,it is well known that the understructure (e.g.,grain boundary) affects the material strength.At atomic level,the crystallographic understructure means the distortion of atomic arrangement;grain boundary;e.g.domain wall.In order to understand the strength of nanocomponents,the both effects have to be clarified.Thus,we have investigated the mechanical behavior of nano-components by ab initio computational simulations1-3.
