Competition And Innovation In Markets With Technology Leaders, Ku-Chu Tsao, Arijit Mukherjee, Achintya Ray

Economics and Finance Faculty Research

In this article, we consider technology leaders (which are innovators) and technology followers (which are non-innovators) to provide a new theoretical explanation for the well-cited empirical evidence of an inverted-U relationship between competition and aggregate innovation. We consider a two-stage game with a deterministic Research and Development (R&D) process, where the leaders first determine their R&D investments simultaneously and then all leaders and followers determine their outputs simultaneously. We show that the inverted-U relationship between competition and aggregate innovation occurs if competition is affected by the number of technology followers. However, the presence of more technology leaders decreases individual R&D …

A Combined Molecular Dynamics/Monte Carlo Simulation Of Cu Thin Film Growth On Tin Substrates: Illustration Of Growth Mechanisms And Comparison With Experiments, Reza Namakian, Brian R. Novak, Xiaoman Zhang, Wen Jin Meng, Dorel Moldovan

Faculty Publications

Using a sequential molecular dynamics (MD)/time-stamped force-bias Monte Carlo (tfMC) algorithm to simulate the deposition of Cu species onto a TiN(001) substrate at 600 K, it is shown for the first time that at the very early stage of growth, BCC-Cu grows pseudomorphically on the TiN(001) substrate as a very thin continuous film with the BCC-Cu[001]//TiN[001] growth direction. By increasing the thickness of the Cu thin film, however, the film transforms through the Nishiyama-Wasserman mechanism from BCC into predominantly FCC-Cu with abundant nanotwins, which is the same type of structure obtained in the experiment conducted here via a dc magnetron …
