Description
Summary:In this letter, for the first time to our knowledge, high dc characteristics of AlGaN/GaN/silicon high-electron-mobility transistors transferred onto a thermally enhanced adhesive flexible tape are reported. Transmission line method (TLM) pattern supported on a flexible tape under 0.5% strain exhibits a high current density of 260 mA/mm. DC measurements performed on a representative gate-TLM device (L G = 2 μm) on a flexible tape are presented. Under 0.16 % strain, the device exhibits a maximum drain current of 300 mA/mm for a gate bias of 0 V and a drain bias of 3 V and withstands V DS = 18 V.
