Abstract :
The solid-state reaction between Ti-capped Er thin film and Ge(001) was investigated. The germanide film formed had a smooth morphology with the phase identified as ErGe1.5. The film is highly textured with ErGe1.5 (1100) //Ge(001). ErGe1.5 has a resistivity value ~18 muOmega.cm. The Ti cap was able to delay the erbium oxide formation to higher temperature.
