Problems solved by technology

Accordingly, J.Wager in the United States coated ITO thin films on ZnO substrates [(11) B.J.Norris, J.Anderson, J.F.Wager, et al.Journal of PhysicsD 2003, 36, L105], H.Kawazoe et al. in Japan The heterojunction of n-type ZnO and p-type SCO was used to successfully prepare transparent diodes [(12) H.Kawazoe, H.Yanagi, K.Ueda, and H.Hosono, MRSBulletin 2000, 25, 28], which conceptually aroused Attract people's attention, but these transparent diodes have no application significance, the fundamental reason is that no ideal p-type material has been found

Embodiment 1

[0035] According to CuAlS 2 The stoichiometric ratio is weighed and packed into a glass tube, vacuumized (less than 10 -2 Pa) and sealed with a hydrogen-oxygen flame, the glass tube containing the mixture was slowly heated to 450°C and kept for 24 hours, and then heated to 650°C to 850°C for solid phase reaction, and the reaction time was 24 to 96 hours. After the tube is opened, the powder is ground and repackaged for the second solid-state reaction, and the conditions are similar to the previous ones. The obtained pure phase powder is subjected to SPS sintering at a temperature of 700°C to 850°C and a pressure of 40 to 60 MPa to finally produce a bulk material with p-type conductivity.

[0036] The conductivity test shows that it has p-type conductivity (the Hall coefficient and Seebeck coefficient in Table 1 are both positive), and the conductivity is good. The room temperature conductivity of the sample is about 0.9S / cm, and the conductivity curve with temperature Such a...

Embodiment 2

[0038] According to CuAlS 2 The stoichiometric ratio is weighed and packed into a glass tube, vacuumized (less than 10 -2 Pa) and sealed with a hydrogen-oxygen flame, the glass tube containing the mixture was slowly heated to 450°C and kept for 24 hours, and then heated to 650°C to 850°C for solid phase reaction, and the reaction time was 24 to 96 hours. After the tube is opened, the powder is ground and repackaged for the second solid-state reaction, and the conditions are similar to the previous ones. Put the obtained pure phase powder into a quartz glass tube after isostatic pressing at 200Mpa, and vacuumize (less than 10 -2 Pa) packaging, sintering at 700-900° C. for 6-24 hours, and finally making a bulk material with p-type conductivity for performance testing.

[0039] The performance test result is basically equivalent to that of Example 1.

Embodiment 3

[0041] Using commercially available Cu 2 S and Al 2 S 3 (purity > 99%) according to CuAlS 2 The stoichiometric ratio is weighed and packed into a glass tube, vacuumized (less than 10 -2 Pa) and sealed with a hydrogen-oxygen flame, and according to the method of embodiment 1 or embodiment 2, a bulk material with p-type conductivity is finally made.

[0042] The performance test results are basically the same as 1.

Abstract

The invention relates to a compound of chalcopyrite structure ABQ<2>(Aú¢Cu / Agú”Bú¢Al / Ga / Inú” and Qú¢S / Se / Te), able to be used in p-type transparent conductors and the preparing method thereof, where ABQ<2> belongs to a family of square crystals, space group I4-2d(No.122), able to be regarded as a deformed blende superlattice structure, where orderly tetrahedron array is composed of slightly flat AQ<4> and undeformed BQ<4>, and its peculiar structure determines it has considerable light transmitting and conducting properties. And it can be applied to p-type transparent conductors and the related. And it is a desired material candidate for p-type transparent conductors.

Description

technical field [0001] The present invention relates to a kind of chalcopyrite type material that can be used for p-type transparent conductor and preparation method, relate to the compound of structure type more precisely, general formula is ABQ 2 (A=Cu, Ag; B=Al, Ga, In; Q=S, Se, Te) materials and their preparation methods. It belongs to the field of structural and functional integrated materials. Background technique [0002] Since the first translucent conductive CdO material [(1) K.Badeker, Ann.Phys.Leipzig, 1907, 22, 749] came out in 1907, due to the needs of military and industrial energy, transparent conductor materials have received unprecedented attention and widely used. Taking 2004 as an example, the market volume of flat display related to transparent conductors was about 25 billion US dollars, which shows that the importance of transparent conductor materials is extraordinary [(2) D.S.Ginley, C.Bright, eds., MRS Bulletin, 2000, 25, 15]. Transparent conducto...
