We theoretically investigate the thermopower of silicene systems in an external electric field perpendicular to the silicene sheet. In the absence of the field, we estimate that the thermopower of pure silicene is of order ∼80 μV/K. When a finite field is applied, a comparatively big band gap...

Purpose: The purpose of this paper is to analyze whether China's exports can effectively improve the global competitiveness of other BRICS countries' exports from the perspective of intra-BRICS export trade. Design/methodology/approach: ...

We investigate whether and how executives' social interactions affect their compensation. Using the social networks among 2,936 chief executive officers (CEOs) during 1999-2008, we report that socially connected CEOs receive significantly more similar compensation than non-connected CEOs. This...

We examine how directors with investment banking experience affect a firm's acquisition behavior. We find that the presence of investment banker directors is associated with a higher probability of subsequent acquisitions, and such positive relation is not driven by reverse causality. Focusing...
