Question

An ideal quantum dot for use in TVs does not contain any cadmium due to concerns about disposal. One potential material for this purpose is InP, which adopts the zinc blende (ZnS)structure (face-centered cubic). The unit cell edge length is 5.869 Å.

1. If the quantum dot is shaped like a cube, how many of each type of atom are there in a cubic crystal with edge length of 1.00 nm? (Answer in I atoms, P atoms)

2. If the quantum dot is shaped like a cube, how many of each type of atom are there in a cubic crystal with edge length of 4.00 nm? (Answer in I atoms, P atoms)
