Extremely small crystals composed of 1000 to 100,000 atoms called quantum dots, are being investigated for use in electronic devices.
A- A quantum dot was made of solid silicon in the shape of a sphere with a diameter of 9 Compute the mass of the quantum dot using the density of silicon (2.3 g/cm^3)
b- Explain how many silicon atoms are in the quantum dot?
c- The density of germanium is 5.325 g/cm3. If you made a nine quantum dot of germanium how many GE atoms would it contain? Presume the dot is spherical nm
