Abstract

A SrSnO3 high-frequency field-effect transistor (FET) is demonstrated. The device structure consists of a recessed Schottky-gate FET with a heavily doped cap layer. DC measurements on devices with 0.5- μm gate length and 4- μm source/drain spacing show a maximum drain current of 53 mA/mm and a maximum transconductance of 43.2 mS/mm. Radio frequency (RF) characterization reveals a cut-off frequency, fT , of 1.31 GHz (0.97 GHz) and a maximum oscillation frequency, fmax, of 3.25 (3.25) GHz, after (before) de-embedding. These results represent an important advancement in developing perovskite materials for RF applications.
