Popular experimentally investigated nanotubes are carbon nanotubes, silicon nanotubes, BN nanotubes, WS2, TiO2, ZnO…etc. Some researchers suggest all III-VI compounds such as AlP, GaAs, GaP, InAs…etc to have the possibility to construct nanotubes. Are the suggested compounds synthesized yet in the shape of nanotubes? What are the differences between theory and practice?
