Description
technical field [0001] The invention relates to the field of conductive materials, in particular to a two-dimensional conductive metal organic framework material and a preparation method thereof. Background technique [0002] In recent years, conductive metal-organic framework (Metal-Organic Framework, MOF) materials have developed rapidly, and they have great application prospects in the field of electronics. Among them, the semiconductor properties of MOF materials make them play a vital role in the field of semiconductor devices. With the rapid development of the semiconductor industry and integrated circuits towards nanoscale miniaturization and miniaturization, traditional semiconductor materials such as silicon, germanium and gallium arsenide have gradually reached functional bottlenecks, so it is necessary to develop some novel semiconductor materials to Replace traditional semiconductor materials. Due to the unique structural, chemical and functional diversity of M...
