With this understanding, scientists can control — on an atomic level — the growth of oxide thin - films.
Says Chen, «By controlling the growth kinetics carefully using molecular beam epitaxy, we managed to grow a topological insulator film with controlled thickness on a freshly cleaved BSCCO surface.
Dr. Peden has written or contributed to more than 160 peer - reviewed scientific publications on the kinetics and mechanisms of automobile exhaust catalysis; the development of zeolite catalysts for diesel engine emission control; hydrocarbon reforming over bimetallic catalysts; the structure of hydroprocessing catalysts; the development of novel, supported solid acid catalysts for petroleum refining; the growth and properties of oxide and semiconductor thin films; and model studies of adhesion at metal / metal - oxide interfaces.
The most significant results were related to: i) the effect of vicinal surfaces on the film growth; ii) the films specifically grown for microwave applications: a clear correlation was demonstrated between the surface resistance, the losses and the concentration of high - angle grain boundaries; iii) the effect of film - substrate interdiffusion and its control by epitaxial buffer layer.
