One approach is the use of an InP/InGaAs composite channel MISFET with regrown InGaAs source/drain. When a gate length of 170 nm was used, Id at Vd = 1 V was 1.34 A/mm. Another approach is the fabrication of a vertical FET. In the case of the vertical FET, an electron launcher for the ballistic transportation of electrons was also introduced. In the fabricated device, the width of the channel mesa was 15 nm.
