Dipole-induced modulation of effective work function of metal gate in junctionless FETs

In this work, a metal gate with a high effective work function (Weff) that is suitable for junctionless field-effect transistors (JLFETs) has been fabricated. Weff is modulated by inserting an Al interfacial layer with different thicknesses between the HfO2 dielectric layer and the Pt gate metal. Tr...
