We use time- and angle-resolved photoemission spectroscopy (tr-ARPES) to investigate ultrafast charge transfer in an epitaxial heterostructure made of monolayer WS2 and graphene. This heterostructu...
Silicon carbide is also known as gold steel sand or refractory sand. Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips (production of green silicon carbide needs to ...
Graphite electrode is mainly made of petroleum coke and needle coke as raw materials and coal asphalt as binder through calcination, batching, kneading, molding, roasting, graphitization and machin...
SiC has excellent physical and chemical properties, such as high melting point, high hardness, corrosion resistance and oxidation resistance. Especially in the range of 1800-2000 ℃, SiC has good ab...
