Remark:GaAs pHEMT: Compared with GaAs HEMT, GaAs PHEMT also incorporates InxGa1-xAs,where InxAs is constrained to x < 0.3 for GaAs-based devices. Structures grown with the same lattice constant as HEMT, but different band gaps are simply referred to as lattice-matched HEMTs. |

Growth Methods:MOCVD,MBE
epitaxy = growth of film with a crystallographic relationship between film and substrate homoepitaxy (autoepitaxy, isoepitaxy) = film and substrate are same material heteroepitaxy = film and substrate are different materialsPlease more information of growth methods, please click the following:http://www.powerwaywafer.com/Wafer-Technology.html
