Do returns to schools go up during transition? The not so contrary case of Vietnam [PDF]

open access: yes, 2009
A key stylized fact about transition economies is that the returns to schooling rise as economic reform progresses. Existing research suggests that Vietnam is an exception to this pattern, with a decrease in males’ return from 1992 to 1998, and little ...

Exploring the Potential of Microwave Annealing for Enhancing Si‐based GeSn Lasers

open access: yesAdvanced Materials Technologies, EarlyView.
We explore low‐thermal‐budget microwave annealing to enhance the performance of group‐IV GeSn lasers on Si. Microwave annealing under optimal conditions can simultaneously relax unwanted compressive strain and enhance the material quality of the GeSn active layer, thereby reducing the threshold and increasing the laser operating temperature.
