The effects of molybdenum doping (0-12 at.%) oil the optical and electrical properties of In,03 were investigated using combinatorial sputter deposition in combination with combinatorial analysis techniques. The electrical properties are highly dependent on the deposition temperature and the molybdenum doping concentration. A minimum temperature between 300 degrees C and 400 degrees C is needed to activate the carriers. The maximum mobility is observed at a Mo concentration of 4.4 at.% and is 65.3 cm(2) V-1 s(-1). The maximum conductivity is observed at 5.9 at.% molybdenum doping and is equal to 5000 Omega(-1) cm(-1). The carrier concentration increases with increasing molybdenum doping to a maximum value of 6.6(.)10(20) cm(-3) at a doping concentration of 8.6 at.%. The optical transparency is high (> 80%) in a wide spectral range that is dependent on the process parameters. (c) 2005 Elsevier B.V. All rights reserved.
