Critical dimension measurement
Webto model coherence and critical dimensions in nanowire structures.Amodel was developed recently to describe strain and coherence in axial nanowire heterostructures,11 while the critical dimensions of isotropic coaxial structures12 have been estimated by comparing the strain energy of two dis-crete states of the system. In this paper we provide ...
