"molybdenum ditelluride... chemical vapor deposition (CVD) techniques that facilitate thin film formation through chemical reactions, the researchers have successfully synthesized large-area 4-inch MoTe2 wafers with remarkable purity... The key innovation lies in controlling the work function by depositing a three-dimensional metal onto a two-dimensional semi-metal—effectively modulating barrier layers that prevent charge carriers from entering...
