Lanthanum silicate

Growth of La203 on Si as gate dielectrics is possible using La(thd)3 in an MOCVD process. As pointed out in Section V.A.4, the deposited ultrathin films form an interfacial layer of lanthanum silicate with the substrate deteriorating their electrical properties therefore, alumina was introduced as capping layer. [Pg.975]

In the present study, synthesis of doped ATLS with general formula Laio-x-zAxSi6-yBy027-x/2-y/2-3z/2 (A = Sr B = Al, Fe x = 0- 3 y = 0- 1.5 z = 0 0.67) has been conducted via mechanical activation (MA) of solid precursors and using polymerized ethylene glycol-citric acid polyester precursors (Pechini (Pe)) route. To find optimal parameters of the synthesis, the effect of the dopant nature and its parent compoimds, milling duration, temperature of MA products annealing on the doped ATLS formation has been studied. Phase, structural and microstructural studies have been carried out to clarify the mechanism of Al and Fe-doped lanthanum silicates formation in the mixtures with different parent compounds. [Pg.4]
