## Abstract DCβ and RFβpulsed measurements of AlGaN/GaN HEMTs on high resistive silicon (111) substrate are achieved under probes in the 300β525 K temperature range. Current collapse and heating effects are studied and it demonstrates the high temperature properties of these devices. Hence the pote
AlGaN/GaN HEMTs are realized on a sapphire substrate without a field plate for power applications at microwave frequencies using a new Ar Ο© ions implant-isolation technology. The first results obtained are very good in terms of device isolation.
