| Abstract |
To realize high-performance two-dimensional electronics, it is necessary to form two-dimensional metal-semiconductor junctions with minimized contact resistance. We have developed a chemical method of selectively achieving semiconducting 2H MoTe2 and metallic 1T' MoTe2 by adjusting Te flux. Molybdenum nanoislands were formed on a substrate by electron-beam evaporation, and then they were tellurized with appropriate Te flux to selectively synthesize 2H MoTe2 and 1T' MoTe2. By combining this new phase-selective synthetic strategy with a lithographic technique, in-plane two-dimensional metal-semiconductor junctions composed of the same material can be formed in a selected pattern on the substrate. This method could be utilized for the mass production of high-performance electronic devices based on two-dimensional materials. |
