硒化钽钨晶体TaWSe2照片:
Layered TaWSe2 ternary alloys have been synthesized at 50%-50% W (tungsten) to Ta (tantalum) ratios. While WSe2 is a direct gap semiconductor with high excitonic binding energy and valleytronic properties, 2H-TaSe2 is a metal with charge density waves (incommensurate CDW). It has superconducting transition at around below 1K. These two extreme compositions were alloyed to create 1:1 W:Ta ratio vdW crystals. These crystals are completely new to the community in the bulk as well as monolayer form and many of its properties are awaiting to be explored.
