Diethylzinc is useful for the deposition of crystalline zinc films by means of plasma-assisted CVD. This product, in combination with molecular oxygen or water, is the most commonly used zinc metal-organic precursor for the growth of ZnO thin films by CVD (including MOCVD, PECVD and ALD. DEZn is also one the most common precursors for p-doping of (Al,Ga)In(As,P) layers grown by MOCVD. Epitaxial layers of Zn-doped InP have been grown by low-pressure MOCVD using this product as the p-dopant source. ZnEt2, in combination with H2S as a sulfur source, has been applied for the ZnS thin films by ALD. See links below

Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging. For additional analytical information or details about purchasing ZN7200 contact us at
