Abstract

High electron mobility thin films of In2−xWxO3+d (0 ≤ × ≤ 0.075) were prepared by pulsed laser deposition. The highest mobility polycrystalline and textured films show mobility >110 cm2/Vs on both amorphous SiO2 and single crystal yttria-stabilized zirconia substrates. The carrier density is in the range 1−3 × 1020 cm−3 at room temperature. The W dopant concentration for films with optimized electrical properties was x ∼ 0.03.
