ocr_text: Challenges in III-V/Si Hetero-Epitaxy\n» A specific defect is antiphase-domains (APD) due to the lack of inversion symmetry of\nIII-V materials --> the sub-lattices are occupied by different atom species.\nThe bonds are polar due to the difference in the ionicity of the constituent atoms.\n===) APDs are inherent to polar-on-non-polar growth. Single layer steps produce 2\ndomains in the III-V overlayer whereas double-layer steps do not. @\nLL BY ii [1101=" (qjang Li et al.
