Brus equation emission energy Δ"E" = "hc"/λ, where c is the speed of light). This is useful for calculating the radius of a quantum dot from experimentally determined parameters. The overall equation is "E", "m"*, and "m"* are unique for each nanocrystal composition. For example, with CdSe nanocrystals: Brus equation The Brus equation can be used to describe the emission energy of quantum dot semiconductor nanocrystals (such as CdSe nanocrystals) in terms of the band gap energy "E", Planck's constant "h", the radius of the quantum dot "r", as well as the effective mass of the excited electron "m"* and of the
The Fox (What Does the Fox Say?) whether it would communicate with a horse using morse code. In the end, the singers float in the air, continuing to wonder what sound the fox makes, while failing to notice a computer-animated fox behind them, which stands on its hind legs and scat sings (voiced by Vegard), answering their question. Bård finishes the song with a melancholy falsetto and the fox leaves without being seen. With the chord progression of C♯m—B—F♯, the song is written in the key of C♯ dorian, with lead vocal range spanning from C♯3 to F♯5. Listeners noticed that the song has a similar structure
