dc.description.abstractNanograss is a long strip-shaped nanostructure composed of pure silicon. It is created through the use of dry etching in manufacturing pure silicon nanograss arrays, with high density plasma chemically depositing HDP VCD, without the use of any hard masks. Hydrogen is used as the dry etching gas in order to manufacture long and thin nanograss. Then, nanoindenters are used to perform mechanical property analysis ,measuring the hardness, Young’s modulus, buckling characteristics, and loading displacement curves .And the error between the measurement and the structure observed through SEM, TEM, and FIB are compared. There have already been numerous studies on nanograss, such as the use of nanograss as background lighting, multi-layered metal connection structures, and solar-powered batteries in multi-field emission technology. However, the majority of studies have focused on the electric, physical, and chemical properties of nano-materials, and very few study the mechanical properties of nanograss, whether or not there are errors in equipment measuring, the stress and strain behavior of nanograss, or the energy necessary for deformation and destruction. This study uses nanoindenters and optical microscopes for analysis in conjunction with mechanical formulas to analyze the behavior of nanograss arrays when indented, and searches for errors and corrections. The results show that materials measured by nanoindenters or atomic force microscopes have a Young’s modulus of two times the value as calculated directly from nanoindenter due to the shape of imprints, cylindrically arrayed materials, nanograss gaps, and mechanical variables. Thus, a new measuring standard needs to be established in future measurements of mechanical properties of materials instead of current imprinting technology measuring.en_US
