"converts molybdenum disulfide from semi-conductive to metallic, improving band alignment... placed semi-metal layer between metal electrode and 2Dl semiconductor overcoming Fermi-level pinning effects... plasma-deposition achieves surface layer yttrium doping... hyperfine patterned structures, thermal stability after annealing, and solid-state nature, enabled advanced-node wafer-scale integration compatibility... ultra-short channel ballistic 2D transistor ohmic contacts with great switching capabilities"
