Interlayer electronic and mechanical couplings of transitional metal dichalcogenides (TMDs) due to Van der Waals force determine their band structure and Raman modes evolution, respectively. We have synthesized twist-stacked WS2 bilayers with twist angles of 0°, 13°, 30°, 41°, 60°, and 83° via ch...
