Polaritons Increased Coupling Strength When Confined To Nanoscale Semiconductors
June 15, 2011 at 12:13 pm
Breaking photonic news! The high light-matter coupling strength limit of these quasiparticles can be broken if you go below 500 nanometers, according to Penn researchers. Because like, we had totally been going from bulk sizes to one micron! But obviously, as the article notes, "the traits of a bulk material are different than structures of the same material on the nanoscale." Duh! Can't forget surface to volume ratio.
The Penn researchers took care to not use chemical etching, totally opting instead to self-assemble the cadmium sulfide nanowires. After all, as they say in engineering, "that ain't no Etch-a-Sketch! That's one doodle that can't be un-did, homeskillet." Mad surface passivation. Silicon oxide shells, yo!
No seriously guys, you try to read the article and tell us what happened. We need material for our forthcoming series, "UTB Tries To Understand Engineering." Diversity!
