CuAlO2, CuAl1-ÈMgÈO2, CuCrO2,
CuCr1-ÈMgÈO2 and CuAl0.5Cr0.5O2 thin films were
deposited on quartz substrates by sol-gel processing using spin coating technique. The
elemental compositions, synthesis mechanisms, optical transmittance and resistivity of
prepared films were studied. CuAl0.5Cr0.5O2
films had the best characteristics under lower
temperature of synthesis. Optical transmittance of CuAl0.5Cr0.5O2
reached 70 % in visible
region. The resistivity of CuAl0.5Cr0.5O2 was 0,4 kΩ·cm
and was stable with time. Thus,
CuAl0.5Cr0.5O2 films may have potential applications
for transparent optoelectronics as pconductivity
transparent oxides.
Keywords: p-type transparent oxide films; quartz substrate; delafossite structure; sol-gel processing. |
