Optimal LED size is an important topic for high-speed UV-C wireless communication but still lacks sufficient investigation. In this work, we study the size effect of UV-C LEDs based on the entire c…
Regression analysis based methods have shown strong robustness and achieved great success in face recognition. In these methods, convex l1 -norm and nuclear norm are usually utilized to approximate…
We report the growth of direct bandgap single-crystalline Ge 1-x Sn x thin films on unheated substrates by a modified magnetron sputtering system. The Ge 1-x Sn x thin films were deposited on Si, G…
Midwave infrared (3-5 μm) photodetector with high detecting performance at room temperature has always been pursued for wide applications such as remote sensing, medical diagnosis, communication, …
Subset selection, aiming to select the best subset from a ground set with respect to some objective function, is a fundamental problem with applications in many areas, such as combinatorial optimiz…
We report high quality GeSn/GaAs heterostructure photodetectors grown by a modified magnetron sputtering system. A metal-semiconductor-metal photoconductor is fabricated to examine the ability of p…
