HIGHLIGHTS
- who: LO-phonon scattering and colleagues from the Department of Electrical and Computer Engineering, Lehigh University, Bethlehem, PA, USA have published the article: Short Barriers for Lowering Current-Density in, in the Journal: (JOURNAL)
- what: By showing results from QCLs developed over a period of time here the authors show conclusively that short-barrier QCLs are effective in achieving low current-density operation at the cost of a reduction in peak temperature performance. The authors show that shorter (and hence thicker) barriers could be utilized for such terahertz QCLs to mitigate the role of IR . . .
