Abstract
Semiconductor compounds and a method for producing the same are provided wherein a method for growing at least one epitaxial layer of a II-VI semiconductor compound using MOVPE is used, the method including the steps of subjecting a substrate to organometallic and hydride precursor compounds in a MOVPE reactor at ultra low pressure, i.e. a pressure in the range of about 10 to 1 mTorr, whereby the organometallic and hydride precursor compounds react at a substrate surface without substantial reaction in the gas phase. The epitaxial layers and semiconductor compounds are useful in blue laser devices.
