Prof. Lev Kantorovich from the School of Natural and Mathematical Sciences, King’ s College London will give a seminar on Wednesday the 13th of April, at 2 pm (room ENG209 in the Engineering Hub, building 13 on the university map). Please join us in attending this interesting talk on graphene growth.
Theoretical modelling of early stages of graphene growth by epitaxial methods
One method of growing epitaxial graphene is temperature programmed growth (TPG). In this method hydrocarbon molecules are deposited onto a transition metal surface at room temperature and then the temperature is increased in order to facilitate the thermal decomposition of the hydrocarbons and lead to the formation of graphene flakes.
The thermal decomposition mechanism of ethylene was investigated with a combined approach of experimental and theoretical techniques. X-ray photoelectron spectroscopy (XPS) experiments were used along with core level binding energy calculations to identify the evolution of species…
