Metal-Semiconductor Field Effect Transistors (MESFETs) are fabricated on hydrogen terminated chemical vapour deposited diamond substrate with sub-micron gate length. Ohmic contacts and passivation technologies are optimized for power applications. DC and RF preliminary measurements are performed and encouraging results in terms of hydrogen termination stability are achieved. Drain to Source current...
Sub-micron gate length Metal Semiconductor Field Effect Transistors (MESFETs) have been realized on polycrystalline diamond samples supplied by Element Six Ltd. and by Russian Academy of Science. RF performances are shown for devices realized on polycrystalline diamond samples of different quality, stating the successfully improvement and reliability of realization technology.
Diamond is one of the suitable semi-conductor for vacuum electronics replacement in high power and high frequency applications. Sub-micron gate-length (200 nm) Metal Semiconductor Field Effect Transistor (MESFETs) have been fabricated on h-terminated polycrystalline diamond and characterized in order to investigate the possibility of RFICs integration. High power (Pout=1.5 W/mm) and high frequency...
Metal-Semiconductor field effect transistor (MESFETs) were fabricated on hydrogen-terminated polycrystalline diamond. Fabricated MESFETs typically showed high drain-source current (140 mA/mm) and large transconductance values (60 mS/mm), with a cut off frequency fT=10 GHz and a maximum oscillation frequency, fMAX, up to 35 GHz. These values suggest device microwave operation in the K- band and are...
