The film surface became smoother with increasing [H] to 1%, but nucleation and growth of grains were apparent above [H] = 1.5%. The width of columnar grains in the ≤200 nm-thick films narrowed from ≈100 nm to ≈50 nm with increasing [H] from 0% to 1.5%. Randomly oriented and agglomerated grains were observed for the film deposited with [H] = 3.6%. Hydrogen added to the working gas induced reduction of the grain size, and then resulted in lowering of the carrier mobility.}, pages = {2365--2368}, title = {Effects of hydrogen in working gas for sputter-deposition on surface morphology and microstructure of indium tin oxide thin films grown at room temperature}, volume = {63}, year = {2009}, yomi = {コヒキ, シゲミ} }
