Abstract: A structure includes a p-doped thin layer and an oxide high-k gate dielectric layer doped with Cd, As, Cr, Pd, Sc, V, Sn, Mo, Mn, Ti, Ge, Ag, Ni, In, or Ga within a fractional (x) limit 0<x<0.25, wherein the thin layer has a thickness of 10 nm or less, and another structure includes a p-doped transition metal dichalcogenide layer with a binary oxide high-k gate dielectric layer doped with V, Sn, Mo, Mn, Ti, Ge, Ag, Ni, In, or Ga within a fractional (x) limit 0<x<0.2. A method for p-doping a thin layer includes doping an oxide high-k gate dielectric layer with Cd, As, Cr, Pd, Sc, V, Sn, Mo, Mn, Ti, Ge, Ag, Ni, In, or Ga within a fractional (x) limit 0<x<0.25 to thereby p-dope the thin layer by surface charge transfer doping, wherein the thin layer has a thickness of 10 nm or less.
