Abstract

The present invention is pulse laser deposition (PLD) process for preparing p-type compound CuAlS2 in chalcopyrite structure and transparent doped conducting film. The PLD process prepares p-type compound CuAlS2 or doped film on the substrate of quartz glass, common glass or Si chip by using the compound block obtained through solid phase reaction and SPS sintering or no-pressure sintering as thetarget and under proper conditions of atmospheric pressure, substrate temperature, and laser strength and frequency. The prepared CuAlS2 film has p-type conductivity, high conductivity, high visible light transparency and other excellent optoelectronic performance, and may find its broad application foreground in electronics and optoelectronics.

Description

technical field The invention relates to a chalcopyrite structure compound CuAlS which can be used for p-type transparent conductors 2 The method of film preparation. The invention belongs to the technical field of transparent conductive material (TCM) film. Background technique A transparent conductor is a material that is highly transparent in the visible region and has good electrical conductivity. In 1907, Badeker first reported the translucent conductive CdO material [K.Badeker, Ann.Phys.Leipzig1907, 22, 749], which attracted people's attention. Until World War II, due to military needs, transparent conductors were widely valued and applied. Transparent conductors are basically oxides, also known as transparent conducting oxides (TCO). TCO can be divided into n-type and p-type according to the conductivity characteristics. n-type TCO materials such as In 2 o 3 :Sn(ITO), SnO 2 :F(FTO) and Zn:Al(AZO), as transparent electrodes, have been widely used in flat displa...
