Semiconducting high manganese silicide (HMS) MnSi1.7 precipitates and thin films have been synthesized by ion implantation. High-resolution transmission electron microscopy (HRTEM) was employed to investigate the crystalline structures. The equilibrium phase of MnSi1.7, i.e., Mn4Si7, was synthesized in all samples. Optical absorption spectra obtained by transmission measurements demonstrated the existence of a direct band gap in all samples. The band gap energies varied ranging from 0.77 to 0.93 eV, possibly due to variation in the strain state associated with different microstructures.
