A multidimensional semiconductor laser simulator is presented which follows a rate equation approach for the coupling between optics and electronics. Capture and emission rates for the bound and free ...

Your poop could be yellow for a number of reasons—like something you ate or something going on in your digestive system.

We fabricated highly reliable carbon nanotube (CNT) field emitters and evaluated their performances in a harsh environment of a tiny vacuum-sealed vessel for vacuum electronic devices. The CNT paste ...
