Schottky Barrier Height Modulation of NiGe/Ge Junction by P and Chalcogen (S, Se, or Te) Co-introduction for Metal Source/Drain Ge nMOSFETs
The profiles and J-V characteristics of P-and/or chalcogen (S,Se,or Te)-introduced Ge substrates and NiGe/Ge diodes have been investigated for a Ge nMOSFET with a NiGe source/drain.We found that chalcogen and P co-introduction caused a greater increase in the number of electrons in Ge than only P introduction.Moreover,P introduction and P and chalcogen co-introduction resulted in lower (higher) Schottky barrier height (SBH) values for NiGe/nGe (NiGe/pGe) diodes than no impurity introduction.Te and P co-introduction was most effective in modulating the SBH.
