Description

We used 395-nm and 790-nm femtosecond laser pulses to deposit aluminum-doped zinc oxide films by pulsed laser deposition. Electrical resistivity of the films was lowered (5.6 x 104(Omega) cm) at 200 degree(s)C for the 395-nm laser pulses, while maintaining the optical transparency. In addition, the deposition rate increased six times. Optical emission was measured to compare the plumes generated by 395-nm and 790-nm laser pulses. We found that the emission from ions was suppressed relative to neutral atoms. Also the kinetic energy of ejected species was nearly doubled for the 395-nm laser pulses.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
