We introduce the concept of electric-field-tailoring in MBE-grown vert
ical metal-oxide semiconductor field-effect transistors (MOS-FETs) and
show that significant improvements in terms of supply voltage, curren
t and speed are achievable in such MOSFETs by employing a planar-doped
-barrier MOSFET (PDBFET) concept. Investigation of electrical characte
ristics and carrier transport in sub-100 nm channel PDBFETs shows the
predicted improvements compared with classical MOSFETs. (C) 1998 Elsev
