Question 18 1 pts Consider PbTe nanocrystals to be used for photodetector applications. These nanocrystals should detect light 700 nm and shorter (1.77 eV and higher energy). What diameter PbTe nanocrystals should you target to use in this application? Assume E Pote - 0.32 eV, Epste -500, and m - 0.01mo. 5.1 nm 23 nm 10,4 nm 15.9 nm
