Abstract :
p/sup +/-AlInAs/InP junction field-effect transistors (FETs) have been fabricated in semi-insulating InP:Fe using ion implantation and a selective molecular-beam epitaxy (MBE) technique. Current-voltage measurements on 4.0- mu m gate-length devices show a zero-gate-bias transconductance of 41 mS/mm, and RF measurements indicate a unity-power-gain frequency of 3.2 GHz. These results indicate that the selective growth method is a viable technique for fabricating high-frequency, high-power junction FETs in the InP-based materials system.<>
