· Ti1 Fe1 Se1

Ti1Fe1Se1 is an intermetallic semiconductor compound combining titanium, iron, and selenium in a 1:1:1 stoichiometry. This material belongs to the family of ternary transition metal chalcogenides and is primarily investigated in research contexts for its electronic and thermal properties. Industrial adoption remains limited, but the material shows promise in thermoelectric applications and as a potential photovoltaic absorber layer due to its semiconducting character and the favorable electronic properties that emerge from the titanium-iron-selenium system.
