Title: Innovations of Xiankun Zhang in Two-Dimensional Materials

Introduction

Xiankun Zhang is a prominent inventor based in Beijing, China. He has made significant contributions to the field of two-dimensional materials, particularly in the preparation and application of molybdenum disulfide (MoS2). With a total of 2 patents, his work is paving the way for advancements in semiconductor technology.

Latest Patents

Zhang's latest patents include a preparation method and use of two-dimensional MoS2 materials. This innovative method utilizes molybdenum source and sulfur powder as raw materials, with inert gas serving as the carrier gas. Through an intermediate evaporation process, these materials are transported to a molten glass surface, where they are deposited into solid molybdenum sulfide. The subsequent etching-spreading-sulfurization-precipitation process yields ultra-high quality and ultra-large area MoS2 single-crystal domains under normal pressure and without hydrogenation. The size of the prepared 2D MoS2 material can reach 1.5 cm, which can then grow into a wafer-level 2D MoS2 material measuring 2 inches in size and 1-2 layers in thickness.

Another notable patent is the metal-semiconductor contact structure based on two-dimensional semimetal electrodes. This structure includes a semiconductor module and a metal electrode module, where the semiconductor module is a 2D semiconductor material, and the metal electrode module is a 2D semimetal material with no dangling bonds on its surface. The interface between the 2D semiconductor material and the 2D semimetal material features a Van der Waals interface with a surface roughness of 0.01-1 nanometer and a spacing of less than 1 nm.
