상세내용 Abstract
The mechanical properties and fracture behavior of individual InAs nanowires (NWs) were investigated
under uniaxial tensile loading in a transmission electron microscope. The InAs NWs exhibited elastic
deformation during the tensile test till fracture and the experiments revealed a brittle fracture on the (111)
plane of a zinc-blende structure. Hemi-ellipse-shaped notches with various radii of curvature, formed via
a focused electron beam, were utilized to investigate the fracture behavior when there is a structural
flaw at the nanometer scale. The dimensions of notches are controlled with proper understanding of
electron beam irradiation on the InAs material system. The stress concentration phenomena with
dependence on the notch size are demonstrated in the InAs NWs by analyzing the results from a finite
element method simulation.
