Alphas-phase aluminum alloyed iron-silicide, α-FeSi(Al) grown at 600 °C.
Highly texture α-FeSi(Al) grown by using conventional sputter.
The α-FeSi(Al) ternary alloy has high work function of ∼5.3 eV.
Transition temperature of α-phase FeSi2 reduces to 600 °C through Al incorporation.
α-FeSi(Al) suitable for renewable energy and electronic applications.
