Abstract:We studied the initial reaction mechanism of Zn precursors, namely, di-methylzinc (Zn(CH 3 ) 2 , DMZ) and diethylzinc (Zn(C 2 H 5 ) 2 , DEZ), for zinc oxide thin-film growth on a Si (001) surface using density functional theory. We calculated the migration and reaction energy barriers for DMZ and DEZ on a fully hydroxylized Si (001) surface. The Zn atom of DMZ or DEZ was adsorbed on an O atom of a hydroxyl (-OH) due to the lone pair electrons of the O atom on the Si (001) surface. The adsorbed DMZ or DEZ migra… Show more
