Capital structure is considered one of the most debatable and controversial subjects in corporate finance. However, little is known about capital structure determinants of firms in the South Asian region. This study attempts to address the gap by not only investigate the impact of firm and country‐specific factors on firms' capital structure across the South Asian Association for Regional Cooperation (SAARC) region but also offer a cross‐country comparison. Results reveal significant relationships between tangibility, profitability, liquidity, firm size, stock market development, economic growth and firm leverage, suggesting that firms in the region are more likely to make their capital structure decisions following pecking order theory. We also find significant differences across countries and debt maturities.

With the growth of the global electric vehicle industry, Viet Nam is proud to be one of the countries with an electric vehicle manufacturing company. This study will focus on government support, environmental perception, pricing perception, infrastructure attributes, and performance factors impacting the purchase intention of electric cars based on the theory of planned behavior (TPB) with variables mediators are attitude and subjective norms. A nationwide questionnaire survey of all ages with 406 valid samples was conducted from December 2021 to January 2022. The result showed that government support, environmental perception, pricing perception, infrastructure attributes, and performance factors positively influence both attitude and subjective norms, according to the SEM results, and attitude and subjective norms have a positive impact on Vietnamese people's intention to buy electric cars. The report has since provided guidance to the government and businesses on stimulating the growth of the electric car sector.

Far-infrared cyclotron resonance (CR) experiments in a selectively doped AlxGa1−xAs -GaAs heterojunction are presented. Quantum oscillations appear in the CR line amplitude as theoretically predicted for a two-dimensional electron gas. The CR linewidth is found to depend on the infrared photon energy, and its correlation with the static mobility is interpreted in the framework of the Ando and Uemura’s model for a two-dimensional electron gas in a high magnetic field.
