National University of Singapore (NUS) physicists found that contacts made of molybdenum disulphide (MoS2) and tungsten diselenide (WSe2) on gold metal are both p-type, while the same contacts with chalcogen vacancy defects become n-type. Non-local exchange and correlation effects are critical in determining the energy level alignment and the contact polarity. Their results show that the...
