Title:
GATE TUBE DEVICE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/062198
Kind Code:
A1
Abstract:
A gate tube device and a preparation method therefor, applied to the technical field of gate tube devices. The gate tube device comprises a first metal electrode layer (1, 9), a second metal electrode layer (4, 12), and a switch layer. The switch layer is positioned between the first metal electrode layer (1, 9) and the second metal electrode layer (4, 12). The switch layer is one of an AB asymmetric structure, a BA asymmetric structure, an ABA symmetric structure, and a BAB symmetric structure that are formed by alternately stacking chalcogenide material ion providing layers A and chalcogenide material conversion layers B. The chalcogenide material ion providing layers A are made of a less-metallic chalcogenide metal material, and the atomic ratio of a metal element is greater than 0% and less than or equal to 50%. The chalcogenide material conversion layers B are made of a chalcogenide material. The gate tube device provided by the present invention can provide high ON state current, high switch ratio, and low sub-domain slope, can be prepared at low temperate, and has a simple structure, ease of integration, low costs and the like.
