• Molecular orbital calculations based on Pauli principle and Hund rule reveal spin-polarized electronic states of pyramidal zinc blende nanostructures. Four models of pyramidal clusters, comprising six layers, were constructed with the cluster axes parallel to the crystallographic <111> and <100> axes in the zinc blende. Dangling bonds of the bottom of the cluster are terminated by H atoms. The spin multiplicities of the clusters were estimated for GaN, GaAs, and Si. Highly spin-polarized states were induced by the unpaired electrons on the surfaces of the nanostructures. The clusters present paramagnetic properties. The result were compared with the first-principles calculations for GaN, which indicated feasibility of our phenomenological method. Peculiar size dependent properties of spin polarization of pyramidal nanostructures are suggested for fine magnetic measurement.
