Abstract

The MnP thin flms were grown on Si (1 0 0) substrates at 300 and 400 °C using molecular beam epitaxy (MBE). The flms crystallize in an orthorhombic structure. FESEM images indicated that both flms are composed of vertically aligned MnP nanorods. However, the density of the nanorods in the flm grown at 400 °C is higher than that grown at 300 °C, leading to a considerable decrease of resistivity in this sample. Both flms showed a ferromagnetic behavior, but the Curie temperature increased from 275 K for the flm grown at 300 °C to 325 K for the flm grown at 400 °C. Anomalous Hall effect (AHE) and negative magneto-resistance (MR) were observed in the flms. While both flms exhibited a metallic behavior, a higher thermoelectric power factor (PF) was achieved for the flm grown at 400 °C
