By choosing a material that has an appropriate asymmetric lattice mismatch to the host substrate, in this case ErSi2 on Si(001), it is possible to grow one-dimensional epitaxial crystals. ErSi2 nanowires are less than one nanometer high, a few nanometers wide, close to a micron long, crystallographically aligned to 〈110〉Si directions, straight, and atomically regular.

The facet surfaces of a self-organized ErSi2 nanocrystal were observed by the STM with a metal-coated carbon nanotube tip. The 10-nm-scale radius and high aspect ratio of the tip was able to provide detailed images of the facet surfaces. The stereographic STM imaging showed that the nanocrystal had (1 0 5) facets of the tetragonal ErSi2 on all facet surfaces with a 1 × 1 periodicity. Bias-dependent STM images revealed that the facet surface has a bulk-truncated structure consisting of Si dimers and Er atoms. Moreover, scanning tunneling spectroscopy exhibited a difference in density of states between top and facet surfaces.

The magnetic properties of the rare earth disilicides (RSi//2) have been re-investigated. We confirm the occurrence of ferromagnetism in PrSi//2 and antiferromagnetism in GdSi//2, TbSi//2 and HoSi//2. NdSi//2 orders at T//N equals 10 K and ErSi//2 orders
