Abstract :
In this paper, we present an in-depth investigation on the effects of epitaxial lift-off (ELO) on GaAs MESFET´s. DC and microwave characteristics as well as thermal effects are considered. Devices were fabricated on a GaAs foundry process and transplanted by ELO. ELO is a technology by which epitaxially grown layers are lifted off from their growth substrate and are subsequently re-attached to a new host substrate. Host materials considered are InP, quartz and silicon with resistivities ranging from 11 mΩcm to 50 Ωcm
