Comprehensive understanding of electron mobility and superior performance in sub-10 nm DG ML tetrahex-GeC n-type MOSFETs.

In this study, we have investigated the electron mobility of monolayered (ML) tetrahex-GeC by solving the linearized Boltzmann transport equation (BTE) with the normalized full-band relaxation time approximation (RTA) using density functional theory (DFT). Contrary to what the deformation potential theory (DPT) suggested, the ZA acoustic mode was determined to be the most restrictive for electron mobility, not the LA mode. The electron mobility at 300 K is 803 cm (V s), exceeding the 400 cm (V s) of MoS which was calculated using the same method and measured experimentally.

Do Returnee Executives Value Corporate Philanthropy? Evidence from China.

While past studies have enriched our understanding of the impact of returnee executives on firm market strategy and outcomes, we know relatively little about the relationship between returnee executives and firm nonmarket strategies. Grounded in upper echelons theory, this study explores the relationship between returnee executives and corporate philanthropy, the latter of which is an important nonmarket strategy in emerging economies such as China. Using data on publicly listed Chinese companies from 2010 to 2017, we find that the proportion of returnee executives is negative related to corporate philanthropy.
