Dimethylzinc is widely used as a zinc precursor in the MOCVD/MOVPE. In combination with tBuOH as an oxygen source, it was used for the growth of ZnO films by MOCVD; in combination with phosphine PH₃ as phosphorus source, for the growth of Zn₃P₂ thin films by photoenhanced-CVD. This product also has been applied for the growth of Zn_xCd_1−xSe epilayers by MOCVD. In combination with ^tBu₂S, it has been used for the growth of ZnS by MOVPE. In combination with H₂Se, DMZn was used for the growth of single-crystalline layers of undoped ZnSe on GaAs substrates as well as for the deposition of (100)-oriented ZnCdTe layers by atmospheric-pressure MOVPE. ZnMe₂ is extensively used as p-dopant for the InP layers, Zn-doped AlInAsSb and AlInAsSb/InGaAs MQW structures grown by MOVPE.  See links below
