Temperature dependent experimental results of Schottky-barrier MOSFETs with dopant segregation using fully nickel silicided source and drain contacts are presented. The dependence of the extracted effective Schottky-barrier height (SBH) on the gate voltage clearly shows that use of dopant segregation lowers the effective SBH for electron injection significantly from 0.64 eV down to ∼0.1 eV.
