abstract
indium-tin oxide films have been deposited by reactive electron beam evaporation of ln+sn alloy both in neutral and ionized oxygen environments. a low-energy ion source (fabricated in-house) has been used. films deposited with neutral oxygen exhibited very low optical transmittance (5% at 550 nm). highly transparent (85%) and low-resistivity (5 x 10(-4) omega cm) films have been deposited in ionized oxygen at ambient substrate temperature. optical and electrical properties of the films have been studied as a function of deposition parameters.
